Reputable 17-4 PH Stainless Steel Supplier - Tuolian

17-4 PH stainless steel also known as AISI 630​​​​​. It is a precipitation-hardening martensitic stainless steel that offers high strength, excellent corrosion resistance, & good toughness. This steel is characterized by its ability to undergo a transformation from austenite to martensite during cooling or deformation. That results in improved mechanical properties.

Tuolian 17-4 PH stainless steel consists of carbon, manganese, phosphorus, and other elements. The specific amounts of these elements are carefully controlled to achieve the desired properties of the steel.

At Tuolian, we manufacture 17-4 stainless steel in sheet, plate, bar, wire, pipe, tube, forging, and casting. These forms can be further customized to specific sizes, thicknesses, & surface treatments based on customer requirements.
