1.4116 stainless steel (X50CrMoV15 / 420MoV / 5Cr15MoV) is a high-quality martensitic stainless steel widely used in knife steel, scissors, medical instruments, and precision components. It offers an excellent balance of corrosion resistance, hardness, toughness, and wear resistance, making it one of the most popular materials in the global knife steel market.
With optimized additions of molybdenum (Mo) and vanadium (V), this grade provides improved rust resistance, fine microstructure, and edge stability. It performs well in humid, food-contact, and daily-use environments, making it ideal for both industrial and consumer applications.
Compared with standard 420 stainless steel, 1.4116 offers better corrosion resistance and wear resistance. Compared with higher-carbon grades such as 440C, it provides improved toughness and easier processing, making it a highly practical and cost-effective solution.

Heat to 750–850°C, then cool slowly to relieve internal stress and improve machinability.
Quenching conditions may be adjusted according to the required hardness and end-use application.
Tempering parameters should be selected based on the desired balance of hardness, toughness, and wear resistance.

ZEICIN STEEL specializes in high-carbon martensitic stainless steels such as 440C. Our focus is on cleaner steel, uniform microstructure, stable heat treatment response, and improved corrosion resistance, ensuring longer service life and consistent batch performance.
Our R&D team participates in national-level research programs and key science and technology initiatives. With strong institutional support, we continuously advance the development of high-performance martensitic stainless steels, ensuring ongoing innovation and technical improvement.
We adopt an advanced melting route of EAF, LF, VD, and RS-ESR. This process improves steel cleanliness, refines carbide distribution, 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 such as 440C for knife blades, surgical instruments, and precision components. Our materials deliver stable hardness, excellent wear and corrosion resistance, and consistent edge performance in demanding applications.
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.
