Precipitation Hardening - PH


17-4PH stainless steel, specifically made for marine applications, such as propeller shafts of vessels. Differentiated finish and surface quality characteristics due to the type of application.

N4534 (PH13-8Mo / XM13 / UNS S13800)

Used in applications that require high mechanical strength, toughness, corrosion resistance and corrosion resistance under stress. Used in petrochemical and aviation industries.

N4540 (15-5PH / XM12 / UNS S15500)

Used in applications that require high cross-section toughness and mechanical strength, such as industries manufacturing valve parts, gears, chemicals, paper, aircraft parts and nuclear reactor components.

V630 (17-4PH / UNS S17400)

Precipitation-hardening martensitic stainless steel. It has an excellent combination of mechanical strength and corrosion resistance. Great dimensional stability. Used in aircraft parts, oil field equipment and several other applications.

V631 (17-7 PH)

Semi-austenitic precipitation-hardening stainless steel It has exceptionally high values of mechanical strength, coupled with good corrosion resistance characteristics. Recommended for radio antennas used in vehicles, springs, thrust washers, bearings, surgical instruments, etc.

VAT286QA (ASTM 660)

It has good mechanical resistance with high toughness and good oxidation resistance at high temperatures up to 700°C. It is used for secondary structures of aircrafts and components for turbines and missiles.
