ASME SA516 Grade 65

Suitable for a variety of applications in the Petrochemical, Chemical, Oil & Gas Industries, ASME SA516 Grade 65 is a carbon steel used by worldwide fabricators serving these markets.
The steel grade is used in the fabrication of weldable pressure vessels and boilers due to the materials specific composition and characteristics. Excellent notch toughness coupled with good weldability are consistent typical in this grade.
Masteel UK Limited stock this steel grade which is ordered to international standards with additional stringent restrictions applied to the chemical, mechanical and testing requirements. This ensures that clients who have more complex needs can receive steel from us, ex–stock, to their requirements.
