We are at Veer Impex, committed to offering high-quality SMO 254 Fasteners. We are assured and certified wholesalers and known for providing quality products across the overseas. Veer Impex always carefully supervises the entire production of steels while taking strict quality checkups to offer guaranteed products with the longest lifespan.
Regarding chemical balance, silicon, manganese less than 1%, chromium up to 20%, a nickel less than 18%, molybdenum not more than 6%, and copper up to 1% are included in the chemical composition of SMO 254 fasteners. Due to molybdenum and nitrogen, SMO 254 grade has a strong capacity to resist ordinary corrosion, crevice and pitting. SMO 254 Fasteners is austenitic stainless steel designed for use in the sea and marine situations where corrosion resistance and resistance to other corrosive environments whenever required. SMO 254 has a wide range of qualities, including resistance to stress corrosion cracking and excellent weldability and smooth fabricability. SMO 254 is supplied heat treated by default; however, for further processing as per requirement, it can be heated to 1150-1200 degrees Fahrenheit; nevertheless, water quenching is recommended for further cooling the fasteners.
We take every effective measure to deliver the best and guaranteed products to you. Thereby we use destructive and nondestructive tests after the production before the packaging. Those tests are mechanical, flaring tests, macro and micro tests, hardness tests, chemical tests, etc. Apart from that, this grade finds many needs as an application across different industries.
