01
Stainless & PH Steels
Precipitation-hardening grades 17-4 PH, 15-5 PH and PH 13-8 Mo together with martensitic stainless grades, evaluated with their heat-treatment conditions and mechanical property requirements.
Typical applicationsAerospace structural parts, defense systems, valve and pump components, parts requiring a balance of corrosion resistance and strength.
431 Stainless Steel
X17CrNi16-2·431
Martensitic stainless steel containing chromium and nickel. Achieves high tensile strength through heat treatment, machines and polishes well. Offers good corrosion resistance; common for shafts, bolts and pump parts.
440B Stainless Steel
X90CrMoV18·440B
Martensitic stainless steel with high hardenability and wear resistance. Provides good resistance to oxidation and corrosion and is suitable for elevated-temperature service. Its good machinability makes it suitable for CNC machining, milling and other mechanical processing. Magnetic.
PH 13-8 Mo Stainless Steel
1.4534·X3CrNiMoAl13-8-2·S13800
Special precipitation-hardening stainless steel developed for aerospace. PH 13-8 Mo offers better corrosion resistance than 17-4 PH and 15-5 PH. Magnetic.
17-4 PH Stainless Steel
1.4542·X5CrNiCuNb16-4·630
Widely used precipitation-hardening (PH) stainless steel. Combines corrosion resistance close to austenitic stainless steels with the ability to reach high mechanical strength through heat treatment (H900–H1150), like martensitic grades. Preferred for its high strength and good machinability; suitable for forging, casting and cold forming. Magnetic.
15-5 PH Stainless Steel
1.4545·X5CrNiCu15-5·S15500
High-strength precipitation-hardening stainless steel covered by ASTM A564. Compared with 17-4 PH, 15-5 PH offers better mechanical properties and a cleaner structure. Magnetic, resistant to high temperatures, highly ductile and resistant to seawater.
