17-4PH

Special Alloys: 17-4PH

17-4PH

17-4PH is one of the most widely used precipitation hardening grades. It is characterised by high corrosion resistance, hardness, toughness and strength.

Similar grades: 17-7 PH and 15-5 PH.

Applications: Nuclear Reactors, Gas Turbines and other similar applications.

30KHGSA

Special Alloys: 30KHGSA

30KHGSA

Highly hardenable steel, high wear resistance and durability, designed for heavy-duty machines construction.

The 30HGSA grade carried more restrictive S-sulfur and P-phosphorus approvals in the chemical composition. This improves the properties and quality of the product.

The 30HGSA steel grade is used for products such as spindles, sprockets, levers, clutch parts, gears, flanges and bushings, heavy duty steel axles, shafts, and steel for compressor blades and airplane tubes.
