54–60 HRC. OEM. Export. Certified.
AISI 4140 is the world's most specified chromium-molybdenum engineering steel — known as EN19 in British/Indian standards, 42CrMo4 in German DIN, and SCM440 in Japan. OEM procurement teams, export units, and Tier-1 suppliers specify it by AISI designation. Thakur Industries provides precision induction hardening for AISI 4140 steel with documentation that satisfies international quality requirements — 54–60 HRC, certified Rockwell test reports, batch traceability. Accepted from Punjab, Haryana, Delhi NCR, and shipped all-India.
4140 Applications
AISI 4140 is used wherever engineering drawings call for a universally understood alloy grade — OEM automotive assemblies for export, mold bases and die tooling, hydraulic and pneumatic component shafts, fastener forgings, and heavy-duty machine components. We accept drawings that specify 4140 and process to exact surface hardness and case depth requirements.
