F436 Hardened/ Square Washers manufacturer in india guaranteed best price in india
ASTM F436 Washers are hardened washers with diameters ranging from ¼ inches to 4 inches. The fasteners are made in carbon steel and weathering steel according to the types. Viha Steel & Forging is a leading manufacturer of the F436 Flat Washer and other types of washers. The washers are used to fill in the gaps between fittings, components and between material surface and nuts on the bolts.
The astm f436 square washers are used in applications where the square shaped spaces are to be filled. There are different types by means of material grade. The type 1 washers are made from carbon steel material where the type 3 F436 Lock Washer and others are made from the weathering steel grades. The carbons steels have the advantage of high toughness while the weathering steels have the advantage of self-healing when cracks or damages occur. The F436 Type 3 Washers therefore are useful in corrosive environments where abrasions or cracks could occur because they will form an oxide layer on top and resist further corrosion.
The astm f436 structural washers are used in construction and in frameworks in other industrial applications such as the oil and gas, petroleum, petrochemical and power plant applications. The hardened steel washers astm f436 have hardness up to 45HRC and can withstand great a stress and pressure. The material composition often consists of phosphorus, sulfur, silicon, chromium, nickel and copper. Please feel free to contact us for the ASTM F436 Type 1 Washer Material and prices with different shapes and sizes of them.
