The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.

A387Gr11Cl2 is American standard pressure vessel chromium-molybdenum alloy steel plate. Among A387Gr11Cl2, ASTM A387 is the number of manufacturing technical conditions of "Cr-Mo alloy steel plate for pressure vessels". 387 is the serial number of technical conditions, and Gr11 is grade 11. According to ASME Ⅱ-2007, A387 has 10 levels of 2, 12, 11, 22, 22L, 21, 21L, 5, 9 and 91. Different grades have different chemical compositions and mechanical properties of materials.

ASTM A516 Gr70 pressure vessel plate annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of ASTM A516 Gr70 pressure vessel plate annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. ASTM A516 Gr70 pressure vessel plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
