What We Do
Core Advantages of 1.7131
Its high toughness absorbs sudden shocks and pressure surges. This prevents stainless steel fittings from cracking or leaking, ensuring reliability in harsh environments such as industrial facilities.
Through nitrocarburizing, the surface becomes wear-resistant. The service life of stainless steel tubes is extended, maintenance costs are reduced, and downtime is shortened in demanding applications such as production lines.
Natural rust prevention protects stainless steel piping in wet or chemical-rich environments. Maintains system performance and reduces the need for frequent repairs or replacement.
There is excellent machinability for fast, precise cutting and bending. Simplifies the production process of stainless steel fittings, ensuring high quality and low cost every time.
Outstanding strength to withstand heavy loads without deformation. Keeps stainless steel tubing stable under pressure, making it ideal for high-pressure use in energy or transportation systems.
Material Standards for 1.7131
