This alloy can be processed from all standard machines that are associated with this grade. In the fabrication process, tooling and working surface should be cleaned to avoid any type of contamination. This alloy is readily worked harden. In the manufacturing process, the cold working operation is required for intermediate annealing. This enhances the hardening and avoids the cracking and tearing. The completion of manufacturing it is processed to full annealing operation to lower the internal stress and optimize the resistance to oxidation.
Mainly, it is hot-formed that requires hot working operations in the temperature range between 1149 deg c to 1260 deg c. The hot formed products are rapidly lower down to ensure the maximum resistance property. However, ss 304 is not hardened by heat treatment operations. The solution annealing is a process done after the cooling in temperature between 1010 deg c to 1120 deg c.
These fasteners have great machinability, thus these are readily machinable with standard feeds, cut depths, and machining speeds. Special considering should be taken to prevent work hardening.
Stainless Steel S30400 Bolts have outstanding resistance ability in many reducing environments. These fasteners offer higher resistance to crevice and pitting corrosion in the environments that contain high levels of chlorides. Moreover, it offers good resistance to stress corrosion cracking above 60 deg c temp. It has also good heat resistance property. However, these are not preferred for continuous service in the higher temperatures. These fasteners are highly utilized where the concern is carbide precipitation. Also, it has good performance in marine environments.
We maintain the highest level of quality through our committed professionals and equipped infrastructure. We ensure only the finest quality materials are used for the manufacturing of our products. To ensure the reliability of each fastener, we are providing material test certificates along with deliver made products. The reports include mill test report, raw material test report, nabl test report, disinfection reports, specification guide, welding guide, quality assurance plan and more.
Here we are continuously enhancing the quality of served products. We exercise strict quality control measures for ensuring the accurate dimensions and mechanical properties of offered products. Our quality assurance system assures each product to pass through destructive tests and non-destructive tests.

The utmost concern is taken by us in the packaging section to prevent different types of damages while exporting. We pack these in wooden cases, plywood pallets, wooden cages, wooden cartons with some sort of support. This packaging is also cover with a plastic sheet to protect different contamination while exporting.
