Ferritic, Martensitic and Special Grades FAQ

The market term 'stainless iron' must be resolved to grades such as 410, 420, 430, 440C, 416 or 430F and their condition.

Ferritic, martensitic, duplex and precipitation-hardening materials differ substantially in magnetism, heat treatment, hardness, corrosion and machinability.

Special grades still require confirmation together with wire, bar, round or sheet form and dimensions.

Define grade standard, heat-treatment condition, hardness, chemistry, decarburisation and finish rather than using the market name for acceptance.

Typical uses include cutting parts, shafts, wear components, springs, appliances and parts needing magnetic or heat-treatment response.

Provide standard grade, product form, dimensions, heat treatment, hardness, quantity and application.
