Rajveer Stainless is the professional stockiest as well as supplier of several kinds of plates and sheets. Our product range is inclusive of  SA 387 GR.91 Cl.1 / CL.2 Sheet Plate.  This product has a very high -end application in all types of industries. It has been used in high-pressure vessels and high temperatures. Grade 91 is amazingly versatile plates. They have high chromium compounds which lead to higher corrosion resistance. It has great strength as it also comes from the SA 387 family. This product has a variety of applications because of its splendid attributes like flexibility, weldability, long lastingness, higher temperature adaptability, and accessibility. This grade is the first choice of industries like nuclear power plants, steams, heat exchangers, boilers, thermal reactors, etc. All- in- all, it is widely utilized in the industries where the work is to be done at very high temperatures. It can be availed with variant customizations in respect to its size, dimension, finishing, thickness, and surface works. This is dependent on the specifications of the clients which they want.

ASME SA387 Grade 91 Class 1 / Class 2 Sheet and Plate can be both hot as well as cold rolled. They have several types of differentiated based on their shapes. Some of them are circles, strips, coils, rings, rolls, flats, profiles, polished, shim sheets, etc. Every kind of grade 91 sheets is used for different purposes. 

Grade 91 is composed with components like carbon, manganese, phosphorus, sulphur, and silicon. Also, they are highly rich in chromium and molybdenum compounds which give these plates their amazing resisting qualities. The governing standards for the specifications of this product are ASTM or ASME A 387- 91 class-2 and EN 10 CRMO VNb9-1. It can have the elongation to the minimum range of 18%. This also shows high tensile and yields strengths. The tests that are commonly done for the quality assurance for this grade are positive material intergranular corrosion test, pitting resistance test, flaring tests, flattening test, micro and macro test, chemical analysis, and eddy current test. Also, it needs to provide the certifications like a raw material report, third party report, and radiography reports.
