What does A4-80 mean on a bolt?

The “80” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Therefore, A4-80 is an austenitic, acid proof stainless grade (usually 316 material – 316 or 316L) which has been cold worked to provide a minimum tensile strength of 800N/mm² (MPa).

What is the size of A4-80?

They also have good electric resistivity and the dimensions of the a4-80 hex nut vary according to different standards. They range from 6mm to 30mm in diameter in general.

Is A4 equivalent to 316?

A4 Stainless is often referred to as 316 or 18/10 stainless. As in A2 above, the numbers 18/10 refer to the chromium and nickel content- 18% chromium and 10% nickel.

Is A4 stainless steel the same as 316L?

A4 Stainless Steel A4 Stainless is often referred to as 316 or 18/10 stainless.

What is Grade A4 stainless steel?

A4 Stainless Steel Often called Marine Grade stainless steel. The molybdenum increases the corrosion resistance to withstand attack from many industrial chemicals and solvents and of course, chlorides. Used in the production of inks, photographic chemicals, surgical implants, and the marine environment.

Is A4 stainless stronger than A2?

A2 vs A4 stainless steel strength Whereas grade A4 is stronger than grade A2, and its tensile properties are almost similar to alloy steel grade 8.8.

Which paper is better 70gsm or 80 GSM?

Hence the difference in quality. The great thing about good-quality 70 or 75gsm paper is that it has been made with superior wood fibre. It ends up as thick or even thicker than standard 80gsm paper, so it runs perfectly! Lighter weight, good quality papers are better for the environment.

What does A4-70 mean on a bolt?

The “70” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Therefore, A4-70 is an austenitic, acid proof stainless grade (usually 316 material – 316 or 316L) which has been cold worked to provide a nimimum tensile strength of 700N/mm² (MPa).

Is A4-70 high tensile?

The A4-70 grade has 700MPa tensile strength and A4-80 has 800MPa minimum tensile strength….
