Vision alloy is the number one supplier of steel products. These steel products are commonly manufactured by using high-quality grades and raw materials. We are the number one suppliers of grade A4-80 stainless steel bolts. These bolts are enriched with excellent properties and characteristics. Vision Alloy is one the most famous supplier of stainless steel bolts, fasteners, and other products.
Grade A4-80 stainless steel bolt is made of high quality and superior material. These bolts are being used in multiple industries for various applications. The estimated working temperature for these bolts is below and above 500ºC. These bolts are highly ductile and durable. The chemical composition of this A4-80 grade includes a high amount of molybdenum, chromium, and nickel. It also includes a moderate amount of carbon in it. A4-80 stainless steel bolts also include some amount of nitrogen in them which provide great stability and strength to an alloy.
The A in this grade identifies as austenitic steel. This grade is made by using austenitic steel which provides great strength and ductility to an alloy. Grade A4-80 provides excellent resistance from all types of chemical reactions. It provides great resistance from corrosion, crevice corrosion, and stress cracking. It also provides excellent efficiency to the product. Stress cracking occurs above 60ºC so this grade can easily prevent that.
Bolts are commonly used for firmly joining two or more parts or objects together. Sturdiness, strength, and malleability plays an important role in the manufacturing of these bolts. The tensile and yield strength of these bolts is comparatively higher than of other grades. ( tensile: 800 Mpa/ yield: 600 Mpa).
