High Strength

Strength is a primary requirement for any industrial fasteners or bolting components. Some material grades offers exceptionally high mechanical properties as compared to other alloys and are classified as high tensile or high strength bolting alloys and are prominently used in commercial and high speed automotive industry, aerospace engineering, turbine manufacturing, structural, subsea applications and many more. Some of the grades in this category includes 8.8, 10.9, 12.9, B7, B16, B21, B24, A490, etc.

High Temperature

Alloys with high physical and mechanical integrity at high temperature are of much importance in Fastener Industry. There are many high temperature applications such as in manufacturing furnace and allied equipments, steam turbine manufacturing, metal and mineral refining, metal forming, chemical processing and power generation, etc. 310 Stainless Steel, Alloy 286, Hastelloy, Inconel, Molybdenum, Waspalloy, Rene 41, and many alloy steel grades like Durehete and many other are among high temperature bolting alloys.

Low Temperature

Fasteners capable to sustain considerable amount of impact every while retain its integrity at low temperatures are used for low-temperature bolting applications. Fasteners manufactured from AISI or SAE 4340 alloy and to various ASTM specifications such as A320 L43, L7, L7M, B21, B23, B24 falls under this category.

Weathering Steel

One of the most important category of bolting alloys exhibit high durability and resisting corrosion and erosion caused to drastic year round weather changes and thus promoting longer product life cycle and reducing the cost. Atmospheric conditions corrodes the surface and forms an adherent protective rust or patina, that inhibits further atmospheric corrosion. Weathering steel is well used in manufacturing fasteners that supports bridges, industrial roofing, open framed buildings and other structural and architectural constructions.

Marine Grade

Marine grade bolting class is quite formed with material with resistance to salt water corrosion or erosion coupled with high strength or low temperature properties. Widely used bolting grades falls under stainless steel and copper alloys. Other alternative is high strength alloy steel with corrosion protective coatings, designed to withstand extreme changes in marine environment. Some most common alloys in this category belongs to 316L Stainless steel, Phosphor Bronze, Brass, Monel alloy, Copper and Copper Nickel and PTFE coated Alloy Steel.

Corrosion Resistant

This category of bolting alloys demonstrates resistance to general corrosion, intergranular corrosion localised corrosion, galvanic corrosion or corrosion cracking caused by other environmental conditions. We offer various types of bolting or fasteners across full range of stainless steel alloys, copper alloys, tantalum, zirconium, pure nickel alloy and other corrosion resistant nickel based alloys. Some of these alloys exhibits corrosion resistance with high temperature properties. While some resists stress corrosion cracking with high degree of product life cycle.
