Vision Alloys is highly recognized for A4-70 and A4-80 Stainless Steel Hex Bolt production and exportation. We serve all types of fasteners that are in increasing demand and which will be in increasing demand. We offer complete order customization to our clients, even in packaging as well. We ensure complete safety measures at the delivery time so that no damage to a single unit occurs.
A4 70 Hex Bolt is introduced by using 316L or 316 stainless steel austenite grade in which letter ‘A’ is dedicated to the process called cold working done on A4-70 Stainless Steel Bolt. We serve all grades with clients’ specified dimensions also wherein the range of size is M10 to M100 for A4-70 SS Bolt. Heavy machinery is the prime seeker of hex bolts as they are much more robust based on their shapes of geometry, possessing high tensile strength.
A2-80 Bolt is the fastener of the class having specifications such as ASTM A194 and A193. For instance, Uv A2 80 Bolt are members of the above particulars. Sulphur and silicon are its important element besides phosphorus and manganese, along with nickel by 8 per cent and chromium being 18 per cent added to A2-80 Fasteners. Their size is usually scaled to 24 inches from ½ inches.
Series of 304 stainless steel fasteners, especially 304L and 304 fasteners, create Stainless Steel Grade A2-80. The metal solution used makes a massive improvement in the physical and mechanical properties of the Grade A2-80. It can withstand severe temperatures having 870 Degree C in operation. A4 series of fasteners are typically used for piercing industries or applications as they are used at elevated temperatures, whereas corrosion resistance is its famous attribute.
