Steel and Metals
In-Situ Metallography and Furnace Life Assessment
Blast-furnace relines are decided on condition data, not calendars. TCR reads that data in the plant: in-situ metallography on live equipment, failure analysis of rolls, bearings and furnace components, and remaining-life assessment of reheating furnaces.
Request a QuoteIn brief
TCR tests and certifies steel and inspects the plant that makes it. India’s integrated steel majors, among them Tata Steel, JSW, SAIL, RINL, Jindal Steel & Power and ArcelorMittal Nippon Steel, route incoming raw material and finished product certification through TCR’s classical wet-chemistry laboratory, while ARTiS inspects sponge-iron reformer tubes from Bhilai to Emirates Steel, Abu Dhabi.
Key takeaways
- 9 plant sections, from the coke oven battery to storage and handling, and 8 families of damage mechanism are covered below.
- Steel is tested to ASTM, EN, JIS and IS specifications, among them ASTM A36, A572 and A588 structural steels, A516 and A537 pressure-vessel plate, and A335 and A213 chrome-moly piping and tubes for captive power; the full standards matrix is below.
- 5 marquee engagements are documented on this page, among them ARTiS reformer tube inspection on DRP1 and DRP2 at Emirates Steel Industries, Abu Dhabi, in 2025.
Overview
A steel works needs two things from a laboratory: independent certification of what it buys and sells, and condition data on the furnaces, casters, mills, reformers and captive boilers that make the steel. TCR supplies both, and investigates the failures in between.
- Failures investigated: blast-furnace hearth and copper-plate cracking, coke-oven refractory failure, caster and mill-component fatigue, direct-reduction reformer-tube creep, and captive-boiler tube failures.
- Mechanisms: refractory wear, carburisation, nitriding, metal dusting, and bearing and roll fatigue, with ARTiS on sponge-iron reformer tubes and failure analysis to establish the root cause.
Industry Context
In steel, maintenance events are earnings events. Tata Steel's reline of the G blast furnace at Jamshedpur pulled India's crude steel output down about three percent quarter on quarter in Q4 FY25, and the Blast Furnace 6 reline in the Netherlands drove that region to an EBITDA loss on higher maintenance, spares and capex in FY25.
- Capacity path: from approximately 145 MTPA of installed crude-steel capacity in FY24 to 300 MTPA by 2030 to 2035 under the National Steel Policy.
- Projects in flight: Tata Steel (Kalinganagar Phase II, Meramandali), JSW Steel (Vijayanagar Phase II, Dolvi expansion), SAIL modernisation at Bhilai, Bokaro, Rourkela, Durgapur and IISCO Burnpur, ArcelorMittal Nippon Steel India (Hazira expansion to 15 MTPA), the Vedanta ESL Bokaro programme, and the Tata Steel and JSW Steel hydrogen-DRP demonstration projects.
- Three integrity-load drivers: blast-furnace and coke-oven assets, some now beyond 30 years of operating life; the Direct Reduction Plant sponge-iron route, whose reformer tubes are inspected with ARTiS as in fertiliser plants; and the captive power and waste-heat boilers inside the works, assessed with TCR's boiler RLA practice.
- Chemistry demand: every integrated producer certifies incoming iron ore, coke, limestone, dolomite and alloying additions, and outgoing HR coil, CR coil, plate, structural sections, special bar and wire rod, a large pool of classical wet-chemistry work that matches TCR's chemical analysis capacity.
- Green steel and new scope: hydrogen-based direct reduction brings API 941 high temperature hydrogen attack assessment to carbon and low-alloy steel equipment in hot hydrogen process-gas service; carbon capture on BOF flue gas brings amine-system corrosion qualification; electric arc furnace expansion brings refractory and shell qualification; solar PV at plant sites brings structural-steel testing of module-mounting structures; and hydrogen blending in coke-oven gas brings qualification of equipment prone to hydrogen attack.
Blast furnace campaign-life decisions rest on condition data: refractory state, shell integrity and the metallurgical health of hot equipment. TCR supplies it through in-situ metallography on live plant, failure analysis of rolls, bearings and furnace components, refractory and materials testing, and remaining life assessment of reheating furnaces and process equipment across integrated and secondary steel, a workload that will run for decades on the existing fleet alongside green-steel capex.

Damage Mechanisms We Investigate
Damage in a steel works is set by the equipment: refractory wear in the coke oven, blast furnace and BOF, bearing and roll fatigue in the caster and mills, and creep and carburisation in DRP reformer tubes. Failure analysis establishes which mechanism acted.
| Equipment | Mechanisms |
|---|---|
| Coke oven | Refractory wear and spalling, oven-wall slump, ascension pipe corrosion, gas main fouling, by-product plant amine corrosion |
| Blast furnace | Hearth wear (the critical operating constraint), copper plate cracking, stove refractory degradation, downcomer cracking, gas-cleaning plant corrosion |

| Continuous caster | Mould-copper-plate wear, segment bearing failure, oscillator drive-bearing fatigue, descaling-spray nozzle erosion |
| DRP reformer | Creep on radiant tubes (HK40, HP-Mod, HP-Nb), carburisation, nitriding, metal dusting, pigtail and manifold creep |
| Reheating furnace | Refractory degradation, skid-rail heat loss, recuperator fouling, scale formation on charge |

Service Applications Across the TCR Continuum
A steel plant is simultaneously a producer and a heavy consumer of integrity services. On the production side, the plant certifies its own product, and TCR's role is independent verification: mechanical, chemical, and metallurgical testing of primary steels to ASTM, EN, JIS, and IS specifications.
On the asset side, the plant carries some of the harshest equipment duty in industry: blast furnace shells and stoves, basic oxygen furnace and electric arc furnace hoods, ladles and tundish structures, caster segments, reheating furnace tubes in creep service, rolling mill rolls and gearboxes, and direct reduced iron reformers running the same creep and carburisation mechanisms as fertiliser reformers. Shutdown windows are set by campaign life and relines; procurement risk sits in rolls, refractories, castings, and spares. TCR Engineering and TCR Advanced serve all five stages of TCR's Trusted Relationship Model (see Why TCR) for integrated, secondary, and direct reduction producers.
- Stage One, Sourcing and Procurement
- TCR qualifies rolls, castings, forgings, refractory anchor systems, and structural steel through mechanical, chemical, and metallurgical testing, runs vendor factory audits and original equipment manufacturer qualification for mill equipment, and verifies incoming ferroalloys, scrap-mix inputs, and consumables through the chemical analysis laboratory, with sample picking and loading supervision on high-value procurement.
- Stage Two, Construction and Commissioning
- During expansion projects, mill revamps, and furnace rebuilds, TCR provides baseline non-destructive testing on structural steel and pressure systems, welder certification and procedure qualification per ASME Boiler and Pressure Vessel Code Section IX and AWS D1.1, radiography and ultrasonic testing of critical welds, post-weld heat treatment, and positive material identification, so the rebuilt asset starts its campaign with a documented baseline.
- Stage Three, In-Service
- In operation, TCR deploys thermography of furnace shells, ladles, and torpedo cars for refractory hotspot detection, thickness monitoring of gas cleaning plant and ducting, remote visual inspection of stacks and confined spaces, and oxide scale and corrosion mapping on boiler and power block equipment in captive plants, with risk-based inspection planning per API RP 580 principles adapted to metallurgical plant equipment.
- Stage Four, Shutdown and Turnaround
- During relines, capital shutdowns, and mill stops, TCR inspects blast furnace shell welds, hood and lance systems, crane girders and structural members, reheating furnace tubes with in-situ metallographic replication, direct reduced iron reformer tubes with ARTiS (as deployed at Emirates Steel Industries on DRP1 and DRP2), and captive power boiler pressure parts, supported by turnaround inspection manpower.
- Stage Five, Continuum
- The engineering stage delivers failure analysis of rolls, gears, shafts, and furnace components, remaining life assessment of reheating furnaces, reformers, and captive boilers, fitness for service per API 579-1/ASME FFS-1 on pressure systems, structural stability assessment of ageing mill buildings and crane structures, and contract research including hydrogen-based direct reduced iron materials questions that carry the plant into low-carbon steelmaking.
