Buy 410S stainless steel bars from a certified Chinese manufacturer. Low-carbon martensitic stainless bar ideal for heat resistance, weldability, and oxidation resistance applications.
The 410S stainless steel bar is a low-carbon, non-hardening martensitic alloy modified from 410 stainless steel to improve weldability and reduce hardening tendencies. With 12% chromium and minor alloy additions, 410S retains oxidation resistance at elevated temperatures while avoiding the brittleness common in hardened grades.
As a China-based stainless steel bar exporter, we provide globally certified 410S bars for high-temperature industrial applications including heat exchangers, furnace parts, petrochemical components, and thermal enclosures. We support international standards like ASTM A276, EN 10088, and offer OEM support for bulk orders.

410S has lower carbon content, which improves weldability and minimizes the risk of hardening or cracking after high-temperature exposure.
Yes, 410S is ferromagnetic due to its martensitic structure, making it suitable for magnetic-sensitive applications.
Common uses include furnace parts, heat exchangers, petroleum refinery components, and environments where oxidation resistance without hardening is critical.
Absolutely. We offer Mill Test Certificates (MTC) and support third-party inspection (SGS, TUV, BV) upon customer request.
Yes. Its low carbon content enhances weldability, and it can be welded using conventional techniques with minimal post-weld heat treatment.
