The advantages of ASTM A572 steel sheet, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.
This kind of ASTM A572 steel sheet plate is based on a level structural steel (called mother grade steel), after smelting, steel, its sulfur content is below 1/5 of general steel, section shrinkage rate is above 15%. The mechanical properties of ASTM A572 steel sheet steel plate along the thickness direction (mainly ductility) are called Z-direction properties. The Z-direction performance of the steel plate can be obtained by tensile test of the sample, generally measured by the section shrinkage.
The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has ASTM A572 steel sheet strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and ASTM A572 steel sheet pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.
Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between ASTM A572 steel sheet, hot rolled sheet and cold rolled sheet?
