How to protect astm a537 class 1 low temperature from crack

The company now has astm a537 class 1 low temperature oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than astm a537 class 1 low temperature 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Carbon steel pipe is more often used than alloy steel pipes. Compared with alloy steel pipe, It has the advantage of good performance with lower cost. BBN supplies astm a537 class 1 low temperature most often used carbon steel pipes and tubes of comprehensive grades and specifications. According to its production process, Including seamless steel pipe, erw steel pipe and spiral welded steel pipe.

astm a537 class 1 low temperature, Q345 steel has good comprehensive mechanical properties. Q345 steel also has acceptable low temperature performance, good plasticity and weldability. Q345 steel can be used as structures, mechanical parts, building structures and general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations and bridges. Q345 steel can be used in hot rolling or normalizing state, and can be used in various structures in cold regions below - 40 ℃.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used astm a537 class 1 low temperature, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. astm a537 class 1 low temperature, Q420C steel has good mechanical properties and weldability, good cold and hot workability.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled astm a537 class 1 low temperature plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive astm a537 class 1 low temperature industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
