630 / 1.4542 / 17-4 PH

It is a stainless steel quality that hardens by precipitation. It is produced and stocked under different heat treatment conditions according to the area of use. (According to European norms; PS800, P930, P960, P1070 – According to American norms; H1025, H1075, H1100, H1150 etc.) This material can be supplied as round, square and square, if desired, heat treated or annealed. Although it is steel, it is a stainless steel with good corrosion resistance, high yield strength and high wear resistance, resembling austenitic group stainless steels, exempting its mechanical properties up to 360 ° C. Therefore, its internal structure is stable. This feature is sensitive to many led to its use in practice. 1.4542 has excellent notch impact strength at minus temperatures.

1.4542 steel is suitable for use in marine environments due to its combination of good mechanical properties and corrosion resistance.

1.4542 provides an excellent solution if stronger corrosion resistance and mechanical properties are required than those provided by martensitic steels.

1.4542 is popularly known as AISI 630 or 17-4Ph.

USAGE AREAS: Glass molds, Defense industry, Aviation industry, Medical materials, Valves and pump shafts for special conditions, paper industry, Food industry, Deck equipment, Pressure plates in the plastic processing industry, and finds widespread use in the sports and entertainment industry.
