403 Stainless Steel Sheet

403 Stainless Steel Sheet Supplier in China

403 stainless steel sheet is a martensitic stainless steel widely used across various industrial applications. It is non-magnetic and can be hardened through heat treatment to achieve enhanced mechanical properties. We also provide customization services for size, type, and surface finish to meet diverse project requirements.

Key Features of 403 Stainless Steel Sheet

A standout characteristic of 403 stainless steel is its high hardness, making it ideal for applications requiring wear resistance and durability. It performs exceptionally well in components with cutting edges or those subjected to abrasive conditions. When properly heat-treated, these sheets exhibit high strength and good fatigue resistance. Although their corrosion resistance is lower than that of austenitic stainless steels, they still offer reliable performance in mildly to moderately corrosive environments. This combination of hardness, strength, and moderate corrosion resistance also contributes to excellent wear behavior.

Common Applications of 403 Stainless Steel Sheet

403 stainless steel sheets are used in a variety of sectors. In the medical field, they are often found in surgical instruments, syringes, and needles. They are also commonly used in the production of cutlery and cookware for kitchen applications. The material is suitable for high-strength fasteners such as screws and bolts. Additionally, it is widely employed in power generation equipment, including steam and gas turbine blades. Other typical applications include bushings, buckets, valve parts, missile and rocket components, as well as compressor and turbine parts.

In summary, 403 stainless steel sheet is a versatile and essential material in many industrial fields. Its balance of hardness, strength, and corrosion resistance ensures reliable performance across various demanding applications. Customizable sizing and processing options further improve its adaptability to specialized needs.
