The aforementioned alloy grades contain a high content of chromium, which is why the SA194 Grade 7 Flat Washer is resistant to oxidation corrosion. For instance, grade 410 A194 Grade 7 Material is a basic martensitic stainless steel grade. These martensitic stainless steel nuts  ASTM A194 Gr 7 Nuts contains about 11.5% chromium. Therefore, the astm a194 grade 7l nuts exhibit both exceptional resistance to wear as well as corrosion resistance properties.

The SA 194 Grade 7 Nuts designed according to this specification are intended to be used for high pressure and/or high temperature applications. Hence, grade 410 ASTM A194 Grade 7 Nuts are used in applications involving industries where they are exposed to corrosive media such as chemicals, food, mild acids, water, and air.  Stainless steel bars from which the ASME SA 194 Gr 7 Hex Nut has been produced is to be hot-wrought. Moreover, the alloy of the fasteners needs to be further processed by either undergoing processes like centerless grinding or by cold drawing.

Each of the following alloys AISI 4140/ 4142/ 4145/ 4140H /4142H /4145H/ grade 410 is to conform to the chemical composition requirements that are prescribed by the specification. Tests such as hardness tests, proof of load tests, as well as the cone proof load tests are to be administered to all nuts and ASTM A194 Grade 7 Washer in order to meet the requirements of the specification
