Q355NH weathering steel is a weather-resistant structural steel that is a low-alloy steel series between ordinary steel and stainless steel. It is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel.
The SPA-H weather resistant steel plate is heated to the annealing temperature and kept for a certain period of time, and then it is cooled down after the temperature of the furnace is fully cooled.
After heating the SPA-H steel plate to the normalizing temperature, the internal structure of the SPA-H steel plate is completely transformed into austenite structure, and then air is used as the medium to cool it. This is the heat treatment process. Afte
Meaning of S355J2W steel plate: S is structural steel, 355 is a yield strength of 355MPa, J2 requires -20°impact, and the letter W indicates that the steel has the ability to resist atmospheric corrosion.
S355J0WP weathering steel is atmospheric corrosion resistant steel, which is a low alloy steel series between ordinary steel and stainless steel. Weathering steel is made by adding a small amount of copper, nickel and other corrosion resistant elements to
ASTM A588 steel is a high strength, low alloy structural steel specification with higher strength and higher atmospheric corrosion resistance for structural steels of all shapes, such as Angle, channel and beam, as well as steel and rebar. ASTM A588 steel
09CuPCrNiA weathering steel plate is a kind of weathering steel (that is, atmospheric corrosion resistant steel). 09CuPCrNiA weathering steel plate is commonly used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, prevention
Appearance and effectiveness: The key is caused by the elements of the ASTM A588 GrA steel plate design plan, such as the arc R is too small, the main bone part is not properly set, and the cross-section is not well connected.
Different from ordinary steel plates, ASTM A588 Gr.A weathering steel has good corrosion resistance. Under severe weather such as acid rain, many buildings began to show different degrees of corrosion, which not only affected the buildings, but also affec
The temperature and size of the steel ingot exceed the allowable negative deviation range of ASTM A588 weathering steel. The ingot is too long, the filling is too fast, and the temperature of the ingot is uneven, resulting in non-drum filling, incomplete
