Stainless Steel

Stainless Steels are commonly divided into martensite steel, ferrite steel, austenite steel, duplex (ferritic-austenitic) steel and precipitation hardening stainless steel. S17400 ASTM 2205

Heat Resistant Steel

Heat-resistant steel means one type of steel possesses inoxidizability, enough high-temperature strength and excellent heat- resistant quality under high temperature. Heat resistant steel is divided into oxidation resistant steel and refractory steel according to its performance. Further into Austenitic heat-resistant steel, Martensitic heat-resistant steel, Ferritic heat-resistant steel and Pearlitic heat-resistant steel according to its normalizing.


Superalloy is a kind of metal material that operating under high temperature above 600℃ and certain stress condition for a long time. It holds combination properties, such as exellent high temperature strength, antioxidation and heat resist- ance corrosion property, favourable fatigue property, fracture toughness property. which has become irreplaceable key material of hot end parts for military and civilian gas turbine engine.

Tool Steel

High Speed Steel

High speed steel (abbreviated HSS), a sub-branch of tool steels, commonly used in tool bits and cutting tools. HSS is a complex steel with carbon content 0.70~1.65% generally, and alloying elements composition can reach totally 10~25%. HSS is ferrous based alloys of the Fe–C–X multicomponent system where X represents a group of alloying elements comprising mainly Cr, W or Mo, V, and Co.

Structural Steel

Structural steel means one type of steel conforms to specific strength and forming property grade that is expressed by interruption elongation during the tensile test. Structural steels are normally used to load bearing, and steel strength is a key design standard in those purposes.

Heat treatment is only suitable for specific grades of
stainless steel. When heat treating a stainless the hardening temperatures, including rate of heating, cooling and soaking times will vary due to several factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult with the heat treatment provider for whole guidance on heat treatment of stainless steel grades. We are delighted to help to work with you the special heat treatment based on your special requirements.
