Table Of content

Alloy steel fasteners are well-known for their amazing properties like corrosion resistance, great ductility, durability, high tensile strength, great toughness, stability in elevated temperatures, and many more. These fasteners are a combination of elements like chromium, vanadium, tungsten, and molybdenum in their composition. The addition of these elements in its composition gives the alloy steel fasteners great strength and resistance to corrosion. The alloy fasteners come in different grades, dimensions, and types.

There are alloy fasteners ranging from M12 to M72 in required length and the types differ such as studs, bolts, nuts, washers, and so on. Grade B7 Alloy steel fasteners are produced in a chromium molybdenum alloy and heat-treated by quenched and tempered methods. This product’s method improves the strength of these alloy steel fasteners.

These Alloy steel fasteners go through several tests to ensure that the customers are provided with good quality fasteners. Some of the tests that we conduct are hardness tests, hydrostatic tests, and many more. These Alloy steel fasteners are used in the petrochemical industry, pharmaceutical industry, railways, construction industry, oil, and gas industry, pulp, and paper industry, etc. Other grades/types of alloy steel fasteners are also used in power plant industries, oil drilling applications, heat exchangers, condensers, etc.
