RAW MATERIAL DATA SHEET - Heat Resisting Steel - Grade DIN 1.4982
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.
C (％): 0.07 ~ 0.13
Si (％): ≤ 1.00
Mn (％): 5.50 ~ 7.00
S (％)≤: 0.030
Cr (％): 14.0 ~ 16.0
Ni (％): 9.00 ~ 11.0
Condition: solution treatment
Tensile strength, σb/MPa: 530 min.

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.
Round bar / Wire rod (Diameter): 5.5mm to 450mm
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 W100 - 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.
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.
