  • ASTM A194 Grade 2H Nuts

SA 194 Gr 2H Heavy Hex Nut & A194 2H Material manufacturer in India

The A194 2H Material covers Medium grade Carbon Steel. This steel has been processed by quenching as well as tempering. The standard specification for the ASTM A194 2H Nuts covers carbon, alloy and martensitic stainless steel nuts that are designed with the intent to be used in both high pressure and high temperature service. These A194 Gr 2H Hex Nuts can also be used in a high temperature, high pressure application.

The size range of the ASME SA 194 Grade 2H Heavy Hex Nuts is between ¼ inch through 4 inches and its metric size ranges between M6 through M100 nominal. SA 194 Gr 2H Lock Nut dimensions also covers nuts manufactured from austenitic stainless steel grades in the size range 1⁄4 inch along with the M6 nominal and above. Grade substitutions in the SA 194 2H Coupling Nut without the purchaser’s or consumer’s permission is not allowed. The A 194 2H alloy steel heavy hex nut material can be further processed by either centerless grinding or by cold drawing. In addition to this, the A 194 Gr 2H Hexagon Nuts & 194 2H Structural hex heavy nuts can be left bare or the metal can be plain finished which could contain a light coating of oil.

ASTM A194 Grade 2H Hot Dip Galvanized Heavy Hex Nuts have high strength and are easily available in the market. DH Heavy Hex Thick Nut made from ASTM A194 Grade 2H are used as substitutes for the ASTM A563 grade DH nuts because of the limited availability of DH nuts in certain diameters and finishes.
