How to select standard of nm450 wear-resistance alloy steel

Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel standard of NM450 wear-resistance and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.

SA516GR70N steel is a standardized medium and low temperature pressure vessel. The overall performance is improved and the standard of NM450 wear-resistance product price is higher. The steel plate has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-laminar cracking performance, low carbon equivalent, and strong resistance to sulfur and hydrogen. The products available for steel plates with a thickness of less than 200mm.

API 5L X70 steel plate/pipes, API 5L X70 steel plate/pipes, under API 5L standard, we can regard X70 steel plate/pipes as large diameter pipes. X70 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X70 steel with the demands in mechanical properties of the pipes followed the API specification for grade X70 (YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.

Titanium microalloying is an element of standard of NM450 wear-resistance strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in standard of NM450 wear-resistance tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Boiler steel standard of NM450 wear-resistance inventory: 14*2000*11181, 14*2070*9060, 14*2200*10030, 15*2200*10270, 15*2500*10000, 15*2992*10185, 16*1500*9340, 16*1800*6000, 16*2000*10713, 16*2120*6080, 16*2230*7650, 18.5*2320*6600, 20*1400*11400, 20*2100*7000, 20*2933*7300, 20*3200*4400, 20.9*2851*7000, 21*2100*8810, 21.5*1630*13480.
