1.4024 martensitic stainless steel, also known as X15Cr13 or 410 stainless steel, is a practical engineering stainless steel widely used in valves, shafts, fasteners, turbine parts, and general mechanical components. It provides a reliable balance of mechanical strength, corrosion resistance, and heat resistance, making it suitable for a wide range of industrial applications.
After proper heat treatment, 1.4024 can achieve good mechanical properties, including high strength, stable hardness, and useful impact resistance. This makes it a dependable choice for parts that must work under moderate corrosion, mechanical load, and elevated temperature conditions.
Compared with austenitic stainless steels, 1.4024 offers higher strength and better wear performance after heat treatment. Compared with higher-carbon martensitic grades, it provides better toughness and easier processing, making it a cost-effective material for many engineering uses.
It also provides good oxidation and scaling resistance up to about 649°C, which supports reliable performance in applications exposed to moderate heat.

Heat to 750–800°C, then cool slowly in the furnace to improve machinability and reduce internal stress.
Heat to 980–1030°C, then oil quench or air cool to form a hardened martensitic structure.
Temper at 700–750°C to improve toughness, mechanical stability, and service reliability.

ZEICIN STEEL specializes in high-carbon martensitic stainless steels such as 440C. Our focus is on clean steel production, uniform microstructure, stable heat treatment response, and reliable corrosion performance, helping customers achieve better batch consistency and longer service life.
Our R&D team participates in national-level research programs and key science and technology initiatives. With strong technical support, we continue to improve the development and production of high-performance martensitic stainless steels.
We adopt an advanced melting route of EAF + LF + VD + RS-ESR. This process improves steel cleanliness, refines microstructure, and enhances corrosion resistance and heat treatment stability, resulting in more reliable performance and longer service life.
We focus on the production and optimization of martensitic stainless steels for valves, shafts, pump parts, mechanical fittings, and precision industrial components. Our materials provide stable hardness, reliable strength, and dependable service performance in demanding operating conditions.
Yes. We are a factory. ZEICIN STEEL produces high-quality, cost-effective special steels, including stainless steel, tool & die steel, and high-speed steel. We also have our own import/export license, so we can serve overseas customers directly and support stable supply with batch traceability.
Yes. For first-time cooperation, we can provide a limited quantity of samples for verification (such as grade confirmation, machining trials, or heat-treatment evaluation). Samples can be shipped by international courier, and the courier cost is paid by the buyer. We value honest cooperation and look forward to a long-term win-win partnership.
Our common international payment methods include T/T and L/C. For trade terms, we can also support options such as DDU based on the order. The final payment method and terms can be confirmed according to your country/region, order value, and delivery method.
Our products use standard industrial packaging to ensure safe transportation. If you need custom packaging, please let us know when placing your order.
If the products are in stock, delivery usually takes 5–7 days.
If the products are not in stock, delivery time is about 30–40 days, depending on the order quantity.
