Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality AISI 4130 Nuts And Bolts, which has a number of outstanding features to offer such as easy fitments, rust free, perfect finish, etc. AISI 4130 Hex Head Bolts is soaring alloyed austenitic steel by means of exceptionally good corrosion resistance. AISI 4130 Hex Head Nuts is added by means of copper for also to increase its resistance to robust reducing acids, like sulphuric acid. AISI 4130 Square Bolts’ low content of carbon improves weld power.
The adding of copper content to these AISI 4130 Square Nuts offers it corrosion resistant features higher to the conventional chrome nickel alloy, especially to sulphuric, acetic and phosphoric acids. Meanwhile, these AISI 4130 Eye Bolts are also being offered in different sizes and shapes to our customers. After a surface – hardening treatment such as carburizing (or nitriding for nitriding alloys), these AISI 4130 Eye Nuts are suitable for parts that must withstand wear as well as high stresses.
AISI 4130 T-Bolts find uses in exotic and highly – demanding applications, such as in the turbine blades of jet engines, in spacecraft, and in nuclear reactors. AISI 4130 T-Nuts, which has good mechanical properties at ambient and elevated temperatures of up to 930 Degree F (500 Degree C), is readily fabricated using the common industrial techniques. The characteristics of AISI 4130 Hex Bolts are at the border between stainless steel and nickel due to the high nickel content.
