Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Carbon Steel Nuts And ASTM A307 CS Fasteners Bolts, which have shown good formability in a variety of fabrications. Carbon Steel Counter Sunk Bolts has excellent general corrosion resistance; superior to Grade 316 in most environments, where higher cutting forces are required and more rapid tool wear is typical. Carbon Steel Acorn Nuts has excellent resistance to localized corrosion including inter – granular, pitting and crevice corrosion, where the CPT is generally at least 35 Degree C.
Carbon Steel Lag Bolts is also resistant to chloride stress corrosion cracking (SCC) at temperatures of up to about 150 Degree C. Sachiya Steel International is one of the prominent distributor and stockiest for high quality ASME SA 563 Carbon Steel Dome Nuts, which is similar to Type 904, but has more strength and hardness. Carbon Steel Hex Bolts can be hardened through heat treatment, which brings good ductility for metal fabricators as well as excellent polish ability.
Application of Carbon Steel Coupling Nuts could result in real cost savings when carefully compared to higher – cost alloys to determine if the necessary resistance is obtained in the chosen media. Carbon Steel T-Bolts has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulphuric, phosphoric, and nitric acids.
