EN3506-1 A2-70 is an austenitic, acid proof stainless grade (usually 304 material - 304 or 304L) which has been cold worked to provide a minimum tensile strength of 700 N/mm 2(MPa). Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel.
Grade 7L. Compatible denotes commercially available nut having suitable mechanical properties and dimensional configuration or style which will make it possible to obtain the desired bolt load. Higher strength nuts or nuts of equal strength may be a suitable substitute provided bolt standard allows.
The torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. Torque values calculated from formula T=KDF, where
