High Quality
Precipitation Hardening Steel

Laxcon specializes into the production of 17-4 PH, 15-5 PH & 17-7 PH steels (also known as 1.4542 and AISI 630).

The precipitation hardening (PH) stainless steel grade is a family of corrosion resistant alloys that provide hardness upto three or four times that of an austenitic stainless steel such as type 304 or type 316.

They are used in the oil and gas, nuclear and aerospace industries where a combination of high strength, corrosion resistance and degree of toughness is required. Precipitation hardening is achieved by adding copper, molybdenum, aluminium and titanium either individually or in combination.

Our hardening steel material comes with a slew of features:

High tensile strength, corrision resistance and toughness
High hardness up to 41 HRC
Ideal for component machining with a high resistance to oxidation
Grade confirmation through PMI testing with handheld spectrometer
Ideal for forging and welding applications
