Martensitic non -rusting steel for the remuneration process with excellent mechanical properties - high strength, ductility and machining - with sufficient corrosion resistance. However, the alloy 1.4021 shows a lack of resistance to chlorine, salts and intercrystalline corrosion. The material 1,4021 is a suitable variant for use in steam environments with low concentrations of inorganic acids, dilution, pure water and steam, provided the surface has been treated accordingly.

The material 1,4021 can also be classified as heat -resistant up to 825 ° C. 1.4021 resists sulfur -containing gases and overheated steam. The mechanical properties remain stable in the operating temperature range of 475 - 500 ° C. The timeline strength is negligible above this temperature, whereby only the creep resistance remains high.

This quality is used in various industrial areas, including the production of screws for elevated temperatures, turbine blades, knives, ornamental parts, surgical instruments, sockets, valve seats, strikers, blades, walls, controls, springs, machine parts, compressed forms and slightly stressed bolts in the sectors Automobile, petrochemistry, industrial hydraulics and energy.

The material 1,4021 is characterized by the following features:

• good polishability;
• chemical resistance;
• good forging;
• Very good mechanical properties.

Areas of application of the 1,4021 square tab are:

• Automotive industry
• Chemistry, petrochemistry;
• food industry;
• mechanical engineering;
• Energy industry.
