ASTM A387 steel ASTM A242 corten steel strips specification refers to 6 grades levels of alloy steel plate for elevated temperature applications, classified by chromium and molybdenum content, Grade 11 and Grade 12 has similar chemical content,they can be used in welded ASTM A242 corten steel strips pressure vessels and industrial boilers, and mostly in oil gas and petrochemical industry, generally it is used for transportion of medium at high temperature.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by ASTM A242 corten steel strips metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the ASTM A242 corten steel strips steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

ASTM A242 corten steel strips, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.

The company has our own truck fleet, and can transfer products flexibly and quickly. At the same time, we have large warehouses near the ports of Tianjin and Shanghai, so as to ensure that we can deliver high-quality products to customers in the first time.
