Ubique Alloys Pvt. Ltd is a distinguished manufacturer and stockist of ASTM A194 Grade 7 Nuts, which was first developed to resist attacks by sulfurous acid compounds. ASTM A194 Grade 7 Hex Head Nuts is non hardenable by heat treatment and can only be hardened by cold working. ASTM A194 Grade 7 Square Nuts should not be heated below 927 Degree C (1700 Degree F). ASTM A194 Grade 7 Lock Nuts is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120 Degree F (49 Degree C). ASTM A194 Grade 7 Eye Nuts is used for condensers in fossil and nuclear fueled power generation stations. ASTM A194 Grade 7 Wing Nuts offers higher creep, stress-to-rupture and tensile strength at elevated temperature. ASTM A194 Grade 7 T Nuts cannot be hardened by heat treatment; however the material will harden due to cold working.
ASTM A194 Grade 7 Panel Nuts are molybdenum-bearing austenitic steel with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic steel. In such applications for ASTM A194 Grade 7 Coupling Nuts, however, the acid concentration has a marked influence on the rate of attack and should be carefully determined. Also, the final consignment of ASTM A194 Grade 7 Dome Nuts is well-reviewed before final delivery at the doorsteps of our customers.
