TLV 9258 martensitic Creep-resisting Steel X12CrMoWVNbN10-1-1 Round bar, Flat bar, Stock 1.4906 Forgings, Hot forging & rolling, Heat treatment
TECHNICAL DATA SHEET - DIN X12CrMoWVNbN10-1-1
MATERIAL CATEGORY: Martensitic creep-resisting steel
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.
Martensitic steel - Chromium content is 7～13%, which holds superior high temperature strength, inoxidizability and moisture corrosive resistance,but weldability is not good.

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.
