ASTM A709 bridge steel plate,The company supplies more than 2,000 tons of pressure vessel steel materials to the Nigerian customer for the construction of atmospheric pressure tower in the refinery. This batch of pressure vessel steel materials are tailored according to customer requirements, and the composition and process are newly designed. The performance of the pressure vessel steel materials meets the requirements of properties such as resistance to tempering embrittlement and hydrogen corrosion, and special properties such as good formability, weldability and adaptability to welding process.
The technology center has an innovative team with complete professional categories, reasonable talent levels, high technical level, dedication and professionalism. The innovation team includes professionals in iron and steel metallurgy, pressure processing, metal materials, mechanical and electrical integration, etc. with the project as the link, according to the needs of the task, a reasonably structured innovation team is established to carry out scientific research and innovation activities under the leadership of the technical leader or technical leader.
A387Gr91Cl2 pressure vessel plate is equivalent to the Chinese grade 10Cr9Mo1VNbN steel. ASTM A709 bridge steel plate, A387Gr91Cl2 alloy steel plate not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness and high and stable durable plasticity and thermal strength performance. When the use temperature is lower than 620 ℃, its allowable stress is higher than that of austenitic stainless steel, .
The Egypt customer ordered 130 tons 316L stainless steel plate in stock, and this batch has left port today for its destination today(October 25th, 2019) 316l stainless steel is molybdenum-bearing austenitic stainless steel This material has better corrosion resistant property than 304/314L for it's higher Ni and Mo content (it is considered to be marine grade stainless steel, not suitable for warm sea water treatment) 316L austenitic stainless steel supplied by our company has good formability and weldablity, additionally it is proved to have excellent properties of tensile, creep and stress-rupture strengths in elevated temperature environment,ASTM A709 bridge steel plate.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates For ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the standard requirements The company is a good ASTM A572 grade 50 structural steel plate supplier in the globle market and the head is located in China Welcome to send us inquiry and questions about structural steel plate,ASTM A709 bridge steel plate.
The toughness of steel is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
ASTM A709 bridge steel plate,We had a wonderful trip in Phuket Island, Thailand. At the end of 2019, in order to thank employees for their hard work for a year and enrich their lives, our company organized a pleasant trip to Phuket Island, Thailand. The tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5 o'clock in the afternoon on the 22th December.ASTM A709 bridge steel plate
