- A2 / ASTM-321 Is An 18/8 Stainless Steel Fasteners: This Designates A Metallurgical Content Of 18% Chromium & 8% Nickel.
- A Bolt Marked A2-70 Is A 321 Stainless Steel Fasteners With A 700 N/mm2 Tensile Strength (See Below Table).
The -70 Representing The Tensile Strength Divided By 10.
-50 & -80 Grades Are Also Available But Are Not All That Common. - A2 / 321 Stainless Steel Fasteners Is What Is Known As An Austenitic Stainless Steel 321 Fasteners : It Is (Mostly) Non-Magnetic.
- Though Some Residual Magnetism Can Be Introduced When The Material Is Cold Worked.
- A2 / 321 Stainless Steel Fasteners Is One Of The Most Highly Corrosion-Resistant Materials Available To The Designer And Engineer.
Four Properties of Stainless Steel 321 Fasteners
Stainless steel 321 fasteners use stainless steel as raw materials. Stainless steel 321 fasteners has four properties.1. High temperature resistance. For high hardness, the fasteners has strong oxidation resistance. It cannot work under high temperature and cannot be interfered by high temperature. If the fasteners is passivated after being made out, the temperature resistance will be better.
2. Physical properties. Stainless steel 321 fasteners has higher specific resistance. The specific resistance of stainless steel is higher than that of carbon steel by five times. Standard parts have an expansion factor. Through experiment, if the temperature is higher, the expansion factor of stainless steel 321 fasteners will be improved definitely.
3. Stress capacity. Stainless steel 321 fasteners can endure moderate stress. Although it cannot be compared favorably with high strength bolt, the fasteners can still meet the common requirements.
4. Mechanical properties. High rust resistance and corrosion resistance have close relationship with the features of stainless steel. For standard parts developing constantly, mechanical properties of stainless steel 321 fasteners will be enhanced further.

SS 321 Fasteners Useful Info
Type 321- The most common grade; the classic 18/8 (18% chromium, 8% nickel) stainless steel. Outside of the US it is commonly known as “A2 stainless steel”, in accordance with ISO 3506 (not to be confused with A2 tool steel)
Stainless steel is also much less magnetic than regular steel fasteners though some grades will be slightly magnetic.
18-8 Stainless
18-8 refers to any stainless steel containing approximately 18% chromium and 8% nickel. This is the most common stainless designation for hardware.

Manufacturing Process of 321 Stainless Steel Fasteners
Machining stainless steel Fasteners grade 321 requires low speeds and constant feeds to reduce its tendency to work harden. This steel is tougher than grade 321 stainless steel Fasteners with a long stringy chip; however, using chip breakers is recommended. Welding can be performed using most of the conventional fusion and resistance methods. Oxyacetylene welding should be avoided. AWS E/ER 321 filler metal is recommended.
Conventional hot working processes can be performed. The material should be heated to 1149-1260°C (2100-2300°F); however, it should not be heated below 927°C (1700°F). To optimize corrosion resistance, a post-work annealing is recommended.
Shearing, stamping, heading and drawing are possible with grade 321 stainless steel Fasteners, and post-work annealing is recommended to eliminate internal stresses. Annealing is performed at 1010-1121°C (1850-2050°F), which should be followed by rapid cooling.
Grade 321 stainless steel Fasteners does not respond to heat Treatment
