ASTM equivalent of A633Gr.D spot

The commonly A633Gr.D spot steels used to manufacture pressure parts of boilers mainly include low carbon steel, low alloy structural steel, low alloy heat-resistant steel, austenitic stainless heat-resistant steel and martensitic heat-resistant steel, etc. According to profiles, these boiler steels can be divided into boiler steel plates and boiler steel pipes. Our main A633Gr.D spot boiler steel materials are as follows: A516 Gr 70, A537 class 1 , 16Mo3, Q345R, A204 grade B, A285C, ASTM A387, P355GH and so on.

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional A633Gr.D spot production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of A633Gr.D spot leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

"Mirror" refers to the surface state of A633Gr.D spot stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.

A633Gr.D spot, Q345C steel plate is a kind of weldable low carbon engineering structure material, which is generally produced by continuous rolling mill. The carbon content of Q345C steel plate is less than 0.25%. The yield strength σ0.2 of Q345C steel plate is 300- 800MPa and the yield ratio is 0.65- 0.95. Q345C steel plate has excellent low temperature toughness. That is mainly owe to the solid solution of alloy elements (Mn, Si, Al, Cr, etc.), grain refinement (Nb, V, Ti, etc.), precipitation hardening (Nb, V, Ti, etc.), phase transformation strengthening (Mn, Si, Mo, etc.), and controlled rolling and controlled cooling, etc. new technologies.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
