Alloy Steel Fasteners are made in different alloy types. They have different composition with chromium, vanadium, tungsten and molybdenum inclusive. The addition of these elements in the composition gives the alloys the strength and corrosion resistance. Navstar Steel is one of the leading Alloy Steel Fasteners manufacturers In India and a leading supplier.
The alloy steel fasteners come in different dimensions, grades and types. There are fasteners ranging from 3mm to 200mm in length and the types differ such as studs, bolts, nuts washers and so on. The Grade B7 Alloy Steel Bolts are manufactured in a chromium molybdenum alloy and are heat treated by quenched and tempered methods. This production method improves the strength of the ASTM A193 Grade B7 Nuts.
The applications of these fasteners include power plants, petrochemical industries, oil drilling applications, oil and gas pipe lines and many others. The ASTM Ba94 Alloy Steel Screws are used to fit components together with just screws without the need for nuts or welding procedures. The high heat applications such as exhaust components, heat exchangers and condensers also used these fasteners. The studs or Grade B6 Threaded Rod types are also used to combine two components together by having threads at both ends of the rods. Please contact us for more information and pricing of the products such as the ASTM A194 Grade B7 Nut Bolt and others of your choice.
