TECHNICAL DATA SHEET - DIN X15CrNiSi25-21 & W-Nr 1.4841
MATERIAL CATEGORY: Austenitic corrosion resisting steels
FEATURES AND CLASSIFICATIONS
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.

APPLICATION FIELD
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.

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.
