17-4PH 630 Stainless Steel Bar

Saky Steel's 17-4PH / 630 / 1.4542 is one of the most popular and most commonly used stainless chromium-nickel alloy steels with copper additive, precipitation hardened with martensitic structure. It is characterized by high corrosion resistance while maintaining high strength properties, including hardness. Steel can operate in the temperature range from -29 ℃ to 343 ℃, while retaining relatively good parameters. In addition, the materials in this grade are characterized by relatively good ductility and their corrosion resistance is comparable to 1.4301 / X5CrNi18-10.

Heat-treatment Option:

1 +A: Annealed (full/soft/spheroidizing) 2 +N: Normalized 3 +NT: Normalized and tempered 4 +QT: Quenched and tempered (water/oil) 5 +AT: Solution annealed 6 +P: Precipitation hardened  

Heat Treatment:

Solution treatment (Condition A) — Grade 630 stainless steels are heated at 1040°C for 0.5 h, then air-cooled to 30°C. Small sections of these grades can be oil quenched. Hardening — Grade 630 stainless steels are age-hardened at low temperatures to achieve the required mechanical properties. During the process, superficial discoloration occurs followed by shrinkage at 0.10% for condition H1150, and 0.05% for condition H900.
