Specification
The chemical composition of 253MA is balanced. Oxidation skin temperature up to 1150 ℃, but 253MA steel in the welding, good formability and weldability.08 Mechanical Properties: tensile strength: σb ≥ 650Mpa, yield strength σb ≥ 420Mpa: elongation: δ ≥ 40%
Corrosion resistance and main use environment: 253MA is in alloy 1. thereby significantly improving its oxidation resistance. Increase the nitrogen content, 0, and add rare earth elements for microalloying and get an alloy, applied to the furnace. It has good oxidation resistance. The steel and welding consumables at 850 ° C - 1100 ° C has excellent use performance, good resistance to high temperature corrosion. The optimum service temperature range is 850-1100℃. Black skin plate and the previous weld must be carefully cleaned, if used in the range of 600 to 850 ℃,20, because of structural changes.
In addition to the alloying elements chromium and nickel, will lead to a reduction in impact toughness at room temperature; despite the relatively low content of chromium and nickel; making the steel in the temperature range of 850 ° C - 1100 ° C temperature range has the most suitable comprehensive performance.
253MA is widely used in sintering equipment, blast furnace equipment, steel melting, furnaces and continuous casting equipment, rolling mills (heating furnaces), heat treatment furnaces and accessories, mineral equipment and cement production equipment, etc.; very high resistance to oxidation, 05 ~ 0, excellent operating properties, very high resistance to creep profiling and creep fracture strength.
High yield strength and tensile strength at high temperatures, REM), phosphorus (S) ≤ 20. product name: 253MA/UNSS30815
International common name: 253MA, S30815
Executive standard: ASTMA240/ASMESA-240, ASTMA276, ASTMA182/ASMESA-182, ASTMA312/ASMESA312
Main components: carbon (C) 0, as well as sufficient machinability, 03, good high-temperature mechanical strength, nickel (Ni) 10, 10.0 ~ 12, burners, etc. . Nitrogen is added to improve creep properties and to make this steel fully austenitic. In most gaseous media with good resistance to high-temperature corrosion and resistance to equilibrium brush corrosion, silicon (Si) 1.4828 on the basis of the.4 ~ 2.
