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.

Valve Steel

Valve steel is a subbranch of heat resistant steels, which is a special material for processing the vent valve & intake valve of combustion engines. This steel material is always under the high temperature 450 ~ 900℃ and also in the operating conditions of 3000~7000kPa explosion pressure.

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.

Hard Alloy

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.

Free Cutting Steel

Spring Steel

Spring steel is specialized in producing the spring and elastic components due to its elasticity under the condition of quenching and tempering. The elasticity of steel depends on its capacity of elastic deformation. This allows objects made of spring steel to return to their original shape despite significant bending or twisting occurs.

Bearing Steel

Bearing steel is a type of steel used in the field of fabricating the ball, pin roller, sleeve for antifriction bearing. and also measuring implements, cold-punching die, lead screw and precision components of diesel engine oil pump. Bearing steel is divided into high-carbon chromium bearing steel, carburizing bearing steel, stainless bearing steel, high temperature bearing steel, medium-carbon bearing steel.

Cast Iron

Cast iron is generic terms of alloy consist of iron, carbon and silicon. Carbon content exceeds the eutectic temperature, can remain the volume in the austenitic solid solution Cast iron is iron-carbon alloy with carbon content up to 2%.

Cast Steel

Welding Material

Welding material is generally called consumable material while welding. Such as welding rod, welding wire, metal powder, soldering flux, gas and so on. With the rapid development of welding industry, mainly divided into argon welding, Co2 welding, oxygen cutting, electric welding.

Heat Resistant Steel - Offer From State-owned Military Industrial Enterprise              
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.
Representative Steel grade:
BS EN X6NiCrSiNCe35-25, BS EN X9CrNiSiNCe21-11-2, BS EN X10CrAlSi13, BS EN X10NiCrSiNb35-22, BS EN X15CrNiSi25-4, BS EN X25CrMnNiN25-9-7
Pearlitic steel

Alloying elements are mainly chromium and molybdenum.and gross content is no more than 5%, those steels possess excellent high temperature strength, processing property at temperature 500~600℃,low cost. they are widely used to produce the heat resisting parts at temperature below 600℃,such as boiler steel tubings, turbine impeller, rollor, fastener, high pressure vessel, pipeline. and representative steel grades are 16Mo, 15CrMo, 12Cr1MoV, 12Cr2MoWVTiB, 10Cr2Mo1, 25Cr2Mo1V, 20Cr3MoWV.

Martensitic steel

Chromium content is 7~13%, which holds superior high temperature strength, inoxidizability and moisture corrosive resistance,but weldability is not good. 4Cr9Si2, 4Cr10Si2Mo, BS EN X40CrSiMo10-2, BS EN X12Cr13, BS EN X17CrNi16-2 are used to make the vent valves of internal combustion engine, also belong to Martensitic steels.

Ferrite steels

Contains more chromium, aluminum, silicon, forming monophase ferritic structure with superior inoxidizability, high temperature gaseous corrosion resistant capacity.but its high temperature strength is lower, brittleness of room temperature is larger, not well weldability. steel grades like 1Cr13SiAl, BS EN X6CrAl13, 1Cr25Si2.
Austenitic steels
Contains more austenite formative elements like Chromium, manganese, nitrogien. At temperature above 600℃, which possess superior high temerature strength, structure stability, excellent weldability. and representative steel grades are 1Cr18Ni9Ti(321), 1Cr23Ni13(309), 0Cr25Ni20 (310S), 1Cr25Ni20Si2(314), 2Cr20Mn9Ni2Si2N, 4Cr14Ni14W2Mo, BS EN X15CrNi25-20, BS EN X53CrMnNiN21-9, BS EN X3CrNiMo17-13-3, BS EN X6CrNiTi18-10.

Application field
Heat-resistant steels are widely used in the field of manufacturing the boiler, steam turbine, motive power machine, industrial furnace, and other mechanical parts of aviation, petrochemical engineering operating at high temperature. Those parts must hold the features: high temperature strength, resistance to high temperature oxide etch, enough toughness, excellent machinability, weldability, structure stability based on different usages.
Manufacturing technology - Smelting
Heat resistant steel is generally smelt in electric arc furnace or induction furnace. For higher quality,it should be smelt via technology of vacuum refining and external refining.
Heat treatment practice
Pearlitic refractory steels use normalizing or hardening and tempering.
Martensitic heat resistant steels adopt hardening and tempering to stabilize the structure for excellent composite mechanical properties and high temperature strength.
Ferritic steels don't strengthen via heat treatment, which can be annealed treatment at temperature 650~830℃ in order to remove the internal stress due to the plastic deformation and welding.then rapid cooling through the brittleness temperature ranges of 475℃ quickly.
Austenitic oxidation resistant steels generally adopt high temperature solution treatment in order to get a superior cold deformation quality. While austenitic refractory steels firsly adopt hight temperature solution treatment, then ageing treatment to stabilize the structure at operation temperature above 60 ~ 100℃, separate out the second phase to strengthen the matrix.
Heat resisting cast steels use in the condition of cast, adopt the relevant heat treatments according to heat resistant steels' categories.
