304 stainless steel hex nuts are six-sided fasteners made from 304 stainless steel, an alloy containing 18% chromium and 8% nickel. This composition provides excellent corrosion resistance and strength, making them ideal for various applications

Stainless steel hex nuts are six-sided fasteners used to secure bolts and screws in various applications. They are made from stainless steel, which provides excellent corrosion resistance and strength. Here are some key points:

Features:

• Corrosion Resistance: Excellent resistance to oxidation and many corrosive environments.

• Strength and Durability: High strength and durability, making them suitable for heavy-duty applications.

• Material: Commonly made from grades like 304 and 316 stainless steel

The grade 8 in the A194 Gr 8 Material indicates Stainless steel heavy hex nuts made from AISI 304 grade stainless steel. Since the ASTM A194 Gr.8 Nut specification includes austenitic stainless steel, the mechanical properties of this grade are exceptional. The Sa194 Gr 8 Nut specification material has good tensile strength, good creep strength as well as good resistance to corrosion at elevated temperature.

This is due to both their austenitic structure as well as their chemical composition, which supports as well as enhances their mechanical qualities.  Hence they would be a good choice of fasteners to be used in both high pressure and high temperature environments. It is mandatory that the material used to make ASTM A194 Grade 8 Heavy Hex Nuts specification be free of mercury as well as radioactive contamination.

ASTM A194 Grade 2H hex nuts are high-strength fasteners made from heat-treated carbon steel. They are designed for use in high-pressure and high-temperature applications, providing excellent tensile strength and durability

The 2h in the A194 2h Nuts specifies that the ASTM A194 2h Material has been both Quenched & tempered. The letter H in the Sa194-2h Nuts specification indicates that the fastener has been treated by heat.Common alloying elements used in the specification for the ASTM A194 Grade 2h Material include metals like manganese and silicon with the addition of phosphorus, sulphur and carbon.

These elements give the ASTM A194 Grade 2h Washer additive value like increased strength and enhanced corrosion resistance. Because of the limited availability of the DH nuts in certain diameters and finishes, the ASTM A194 2h Nuts are used as substitutes. The A194 2h Coupling Nut can be wither hot forged or cold punched. The ASTM A194 Grade 2h Material have a higher proof load requirement.
