NDT Methods for Steel Production & Metal Processing

UTUltrasonic Testing

Lamination and internal defect detection in steel plate, slab, and bloom before hot rolling — prevents defective material reaching fabricators

MTMagnetic Particle Testing

Surface and near-surface crack detection on hot-rolled structural shapes, forgings, and cast steel components per ASTM E709

ETEddy Current Testing

High-speed bar and tube seam inspection on the production line — detects seam weld defects at rolling speeds up to 100 m/min

RTRadiographic Testing

Cast steel product acceptance per ASTM E94/E446 and structural steel casting acceptance for bridge and building applications

HardnessHardness Testing

Process verification — ensures heat treatment has achieved target hardness band (e.g., 300–360 HB for abrasion-resistant plate); incoming material verification

Applicable Codes & Regulatory Requirements

ASTM E709 — Guide for MT
ASTM E94 — Guide for RT (film technique)
ASTM E446 — Reference Radiographs for steel castings
AWS D1.1 — Structural Welding Code (for structural steel fabrication)
ASME SA-578 / SA-435 — UT of steel plates (ASME/ASTM)
ABS / USCG for marine
FAA Part 145 / EASA
AS9100

Certifications Typically Required in Mobile, AL

ASNT Level II/III UT, RT, MT, ET

AWS CWI for fabrication-shop weld inspection

ISO 9712 Level II/III (for export product certification)

Typical Steel & Metals Inspection Scope

Steel mill NDT is largely automated or semi-automated and production-integrated: immersion UT systems scan plate at the hot strip mill, eddy-current coils scan bar and tube on the production line, and hardness testers sample every coil or heat. Fabrication NDT (welded structural products) is more manually intensive — AWS D1.1 acceptance, visual inspection of each joint, and UT or RT on complete-joint-penetration welds.

Equipment & Asset Classes Inspected

Steel plate (mill production acceptance)

Structural shapes (I-beams, HSS, angles)

Steel bar and rod (bar and tube mills)

Forgings (flanges, fittings, shafts)

Cast steel components (valve bodies, pump casings, bridge hangers)

Continuous cast slab and bloom

Specialty alloy ingots and billets

Key Defect Concerns in Steel Production & Metal Processing

Laminations from continuous casting inclusion streaks
Hydrogen flaking in thick alloy forgings
Seam defects in hot-rolled bar and tube
Shrinkage cavities in cast steel nodes
Surface seams and laps from hot rolling
Decarburization layer in heat-treated spring steel

Frequently Asked Questions — Steel Production & Metal Processing NDT in Mobile, AL

What is a lamination in steel plate and why does it matter?

A lamination is a planar discontinuity parallel to the plate surface, typically caused by elongation of a non-metallic inclusion during hot rolling. Laminations are generally undetected by surface VT or MT because they lie below the surface and have no surface-opening. They are critical in applications where through-thickness loading occurs — flanges, T-connections, or lamellar-tearing-prone applications per AWS D1.1 Annex K. ASME SA-578 (UT for plate) is the standard inspection for lamination detection; ASME SA-770 covers ultrasonic testing of heavy-wall plate for lamellar tearing susceptibility.

Can NDT Connect source NDT contractors for a steel fabrication project?

Yes. Post your fabrication scope — structural steel per AWS D1.1, pressure vessels per ASME Section VIII, piping per ASME B31.3 — and specify the required coverage (VT only, 10% UT, 100% MT on CJPs, etc.). We connect you with certified AWS CWI-led inspection teams and ASNT Level II NDT crews within your region. For large fabrication projects, multi-crew arrangements with staggered mobilization are available through our contractor network.

When is NDT inspection demand highest for steel & metals in Mobile, AL?

Mobile, AL's steel & metals sector concentrates inspection demand around Avoid hurricane season Jun-Nov — the period when most facilities schedule major outages, turnarounds, or planned maintenance campaigns. Booking NDT contractors 4–8 weeks ahead of your target window is strongly advisable; last-minute mobilization during peak periods typically costs 15–25% more and may mean accepting teams with less local experience. NDT Connect lets you post your scope early, collect quotes, and lock in a preferred contractor before the peak-demand compression begins.
