In English-speaking countries, the following materials are known under AISI 630:
AISI 630 is a hardenable, martensitic stainless steel with high wear resistance, good corrosion resistance and high yield strength.
By combining excellent mechanical properties and high corrosion resistance, AISI 630 can be used in a marine environment, but in standing seawater it is susceptible to crevice corrosion.
17-4 PH is manufactured in several strength levels, for example: in solution annealed (AT) and hardened versions (H900, H925, H1025, H1075, H1100, H1150, H1150M).
We store this steel in solution-annealed design, as well as in condition H1025 and H1150. The AISI 630 material can be use in temperatures up to 450°C, but also suitable in the low temperature range. At minus temperatures an excellent impact strength is given.
Steel 1.4542 can be machined in solution-annealed and hardened condition, but the machinability depends on the hardness.
AISI 630 is used in the aerospace, chemical, petrochemical and petroleum industries, in medical and dental technology, in plant construction and in shipbuilding.
