ASTM A194 Grade 2 Nuts

ASME SA 194 gr 2 Heavy Hex Nuts

Alloy Steel 2 Square Nuts
Table of Content
ASTM A194 is a specification that takes in nuts produced from various grades including steels belonging to martensitic and austenitic stainless steel classes as well as carbon steel and alloy steel. ASTM A194 Grade 2 Nuts Suppliers generally recommend using the material based on the application it is to be used for, while also keeping in check with the economical value required by the buyer. One of the most common materials available across markets includes Alloy Steel 2 Nuts.
They have a much better performance as compared to carbon steels, though the price of these nuts is much higher than the former. Applications that require both high mechanical strength and mild corrosion resistance properties are more likely to make use of alloy steel Sa 194 Gr 2 Nuts. however, in the off chance that the application deals with highly corrosive media, the buyer has the option of ordering corrosion resistant grades such as 316 or 304 Astm A194 Grade 2 Heavy Hex Nuts.
Since this specification acts as a guideline for applications that are involved with high pressure and high temperatures, these nuts are under tremendous stress and are often susceptible to giving in under such loads. If an austenitic alloy is selected in the manufacture of Astm A194 Grade 2 Square Nuts, they are further processed by annealing followed by strain hardening process. Or the nuts could undergo solution hardening to improve its mechanical properties, thereby increasing the ability of the Astm A194 Grade 2 Hex Nuts to withstand high levels of stress caused by either high temperature or high pressure or in some instances both.
