What is an A2-70 screw?

A2-70 Stainless Steel Fastener is recognized by 2 ways, A2 which describe it as being from SS 304 family and 70 which classifies its strength. When we say A2-70 it generally means that the bolt / screw is from SS 304 grade and has an ultimate tensile strength as 70 kg or 700 n/mm2.

What is the size of a A2-70 Nut?

What is the difference between A2-70 and a4 70?

The material composition is the primary difference that makes difference in the mechanical properties and other aspects of these materials. The a4 material has 16% chromium, 2% molybdenum and 10.5% nickel in the composition. The a2 material has 10.5% chromium in the composition.

What does A4 70 mean?

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 A2 same as A2-70?

A2 / ASTM-304 Is An 18/8 Stainless Steel : This Designates A Metallurgical Content Of 18% Chromium & 8% Nickel. A Bolt Marked A2-70 Is A 304 Stainless Steel Bolt With A 700 N/mm2 Tensile Strength (See Below Table).

What is the difference between A2 and A4 screws?

A4 stainless is often used in marine or chemical environments as it has greater corrosion resistance than A2. The chemical composition of both A2 and A4 stainless steel are almost identical with the most notable differences being the higher nickel content and the addition of Molybdenum in A4.

Is 18 8 the same as A2?

A2 stainless steel is often referred to as 304 or 18/8 Stainless. 18/8 actually refers to the amount of chromium and nickel in the alloy – 18% chromium and 8% nickel. A2 (304, 18/8) is an austenitic steel and is non-magnetic. The chromium provides a corrosion and oxidation resistance, however it can tarnish.

What grade is a F593C bolt?

3/8″-16 x 1-1/2″ Plain Finish ASTM F593C Grade 18-8 Hex Washer Flange Bolt | Fastenal.

Is A2 stronger than A4?

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.

What is better A2 or A4 stainless?

A4 stainless fasteners are easier to fabricate, clean, finish and weld, and whilst they are generally more expensive than A2 fasteners, they can be more cost-effective over a longer period of time due to the lack of maintenance or replacement required when used outside.

What is the strongest stainless steel bolt?

BUMAX® Ultra – the world’s strongest bolt

Since its launch in 2014, the BUMAX® Ultra range has proven that it is capable of exceeding tensile strengths of between 1 500 to 1 700 MPa on various applications, with good corrosion resistance and an operating range of between -50 and 400°C.
