Grade A4 is also referred to as stainless steel grade 316 by manufacturers. Considered to have better properties than A2, grade A4 or as also known as 316 Stainless Steel Nuts have a specific tensile strength, which in this case is 700 N/mm2. The tensile strength and grade are often mentioned together. In this case, the tensile strength for A4-70 Nut is about 700 N/mm2, which is represented as 70 after its division by the number 10.

The austenitic grade 316 Stainless Steel Wing Nuts also offer better properties than A2. For eg., the corrosion resistance properties are a tad higher, in different media and across a wider temperature range, making the 316 Stainless Steel Weld Nuts, useful in several chemical process based applications. Since grade 316 is referred to as a sanitary grade, many businesses in the pharma and F&B sector reap its benefits.

Not only is the alloy non-toxic, but the 316 SS Acorn Nuts do not react to cleaning agents, leaving a cleaner and much smoother surface as opposed to regular steels. Its association with being able to function well in seawater is the reason why the A4-70 Nut Material is labelled as marine grade steel.
