TECHNICAL DATA SHEET of Creep-resisting Steel - DIN X8CrNiNb16-13 / 1.4961
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.
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.
C (％): 0.04 ~ 0.10
Si (％): 0.30 ~ 0.60
Mn (％): ≤ 1.50
P (％)≤: 0.035
S (％)≤: 0.015
Mo (％): -
Tensile strength, σb/MPa: 510 ~ 690
Elongation, δ 5≥(％): 35
Heat-resistant steel is 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.
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.
Round bar / Wire rod (Diameter): 5.5mm to 800mm
Square bar / Flat bar: 3mm to 800mm
Length: Fixed length or random length or based on the customer's special requirement.
Sheet steel via cold rolled: T0.5 - 6mm X W6 - 1000mm X L1000 - 2000mm
Steel strip via cold rolled: T0.1 - 3mm X W5 - 200mm X L (or in coil form)
Forging piece: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
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.
