Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 304L Bolts And Nuts, which is considered resistant to potable water with chlorides at ambient temperatures. Stainless Steel 304L Hex Head Bolts is used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food – handling equipment. These Stainless Steel 304L Hex Head Nuts is also used in the architectural field for exterior accents such as water and fire features. Stainless Steel 304L Square Bolts has excellent resistance to a wide range of atmospheric environments and many corrosive media. These Stainless Steel 304L Square Nuts is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60 Degree C.
Stainless Steel 304L U-Bolts of austenitic stainless steels are the most versatile and widely used stainless steels. These Stainless Steel 304L Lock Nuts is commercial grade that exhibit good machinability and have excellent weld – ability characteristics with or without the addition of filler metals.
Stainless Steel 304L Eye Bolts contains both chromium (usually 18 %) and nickel (usually 8 %) metals as the main non – iron constituents. These Stainless Steel 304L Eye Nuts are an austenite steel and contains 17.5 – 20 % chromium, 8 – 11 % nickel, and less than 0.08 % carbon, 2 % manganese, 1 % silicon, 0.045 % phosphorus, and 0.03 % Sulphur.
