We have the largest inventory & ready stock of around 200 tons of SA 387 Grade 91 Class 2 Steel Plate in different size, grades & cuts. Our manufacturing program is supported by intensive in-house product inspection and testing and accredited to meet all the most recognized international standards, including ISO 9001: 2008.
Ninesteel specializes in SA 387 Grade 91 Class 2 Steel Plate. With 25 years of experience in supplying & exporting SA 387 Grade 91 Class 2 Steel Plate we offer high quality, lower cost and the best service. As a result to that our export account today is in over 45 countries some of them are Iran, Saudi Arabia, United Arab Emirates, Singapore and Malaysia. We welcome your inquiries.
We are specialized in offering precision engineered SA 387 Steel Plate, which are used in various engineering applications and can be availed in various grades like ASTM A387 Grade 11 Class 2, Grade 22 Class 2, Grade 5 Class 2, Grade 9 Class 2, Grade 12 Class 2 and Grade 91 Class 2. These grades are available in the form of SA 387 Steel Plate.
SA 387 Grade 91 Class 2 Steel Plate supplied by us are accepted by clients in various spheres of the industries ranging from basic industries such as sugar, paper, textile, dairy, engineering to more complex such as oil & gas, petrochemical, chemical & fertilizers, power generation and nuclear industries. We also have huge ready stock of Chrome Moly Steel Plate, Boiler Plate, HIC plate, Pressure Vessel Steel plate, Abrasion Resistant Steel Plates, Offshore & Structural Steel Plate, Quenched & Tempered Steel plate, High Nickel Alloy plate, Stainless Steel plate, Duplex Stainless Steel Plate, Clad plate and 16MO3 Steel Plate.
Where resistance to high temperature and good anti-corrosion characteristics are required, ASME SA387 Grade 91 Class 2 carbon alloy steel plate is a material to consider. It is a pressure vessel grade steel which is used commonly by fabricators who supply the oil and gas industry. Due to the materials excellent corrosion resistant properties, SA387 Grade 91 is also an option for use in sour service environments. The material has good weldability and with its heat resistant qualities, the material is a highly versatile steel which can be used in numerous applications.
Ninesteel can supply SA387 Grade 91 steel plate from stock to global destinations with mill certification and stampings.
