Medium carbon grade alloys and stainless steel are both covered by the ASTM A194 Stainless Steel Nuts Grade 6 Specifications. Both austenitic and martensitic grade stainless steel are covered by the ASTM A194 Grade 6 Fasteners' requirements.
Table of Content
Applications involving high temperature, high pressure, or both high temperature and high pressure may call for the use of these ASTM A194 Gr. 6 Heavy Hex Nuts. While the Rockwell hardness value on the C scale ranges from 20 to 28C, the Brinell hardness requirement as stated in the ASTM A194 Grade 6 Washer specification falls between 225 Mpa and 271 Mpa.
The SS Gr.6 Fasteners standard covers fasteners with sizes ranging from 14" to 4", and the SS Gr.6 Bolts specification covers metric sizes ranging from metric M6 to a nominal size of M100. Chromium is one of the key ingredients in ASTM A194 Grade 6 Nuts. The A194 Gr 6 Hex Nuts standard fasteners have a chromium concentration that ranges from 11% to 13.5%. These fasteners have desirable mechanical and physical properties like improved tensile strength and increased corrosion resistance thanks to the addition of chromium in the SS Grade 6 Nuts.
