It is an engineering material that takes into account both cost and performance, and is widely used in the fields of electronic appliances, automotive decoration and building hardware.

410 stainless steel plate is a representative of martensitic stainless steel, containing 11.5%-13.5% chromium. It can achieve high hardness (HRC50 or above) and high strength through heat treatment (quenching + tempering), and has excellent wear resistance. Its corrosion resistance is weaker than austenitic steel, but its cost is lower and it is suitable for non-strongly corrosive environments. It is easy to cut and can improve the surface hardness through cold hardening. It is widely used in tools, turbine blades, valve parts, pump shafts and wear-resistant structural parts.

430 stainless steel plate is a representative of ferritic stainless steel, containing 16%-18% chromium, no nickel, low cost and magnetic. Its corrosion resistance is weaker than 304 stainless steel, but it has excellent high temperature oxidation resistance (stable below 800°C), smooth surface and easy processing, suitable for building decoration, home appliance panels, automobile exhaust pipes and tableware manufacturing. After cold processing, the hardness increases, but the ductility decreases. Because it does not contain nickel, it has a significant price advantage and is widely used in scenarios with moderate corrosion resistance requirements and cost control. It is a typical choice for economical stainless steel materials.
