Today I received a inquiry from Saudi Arabia, in the inquiry, the material is SA 387 GRADE 9 CL.2,the products is Spectacle Blind flange , 36″, CL 300. Today let’s learn about the material of SA 387 GRADE 9 CL.2.

Properties of SA 387 GRADE 9 CL.2:

There are many good properties the SA 387 GR.9 CL.2 plate has to offer. This has become possible only with the high quality production of plates. The ability to be excellently resistance to corrosion, pitting, oxidation, stress corrosion cracking, crevice corrosion is making it best to be used at high temperature. It is having high tensile strength, rugged construction, good dimensional accuracy, fine surface finishes, durability, and flexibility and long-lasting and withstanding heavier loads as well.

Testing  of SA 387 GRADE 9 CL.2:

The materials testing in the industry is done mandatorily to make sure that yes the high quality of SA 387 GR.9 CL.2 PLATE is manufactured. The testing also assures that no machine or human error could be responsible for ruining the plate quality and supply faulty product. The testing is conducted by the experts by effectively using advanced tools. Testing done are Intergranular corrosion test, positive material identification test, hardness test, flattening/flaring test, macro/micro test, chemical/mechanical test, pitting resistance test.

Chemical component of ASME SA 387 Grade 9 CL. 2:

C Si Mn P S Cr Mo V
≤0.15 ≤1.0 0.3-0.6 ≤0.03 ≤0.03 8.0-10.0 0.9-1.1 ≤0.04
