Viha Steel and Forging products

Viha Steel & Forging is a leading Super Duplex Fasteners Manufacturer and we produce the fasteners in the 2507 duplex grade. The Super Duplex 2507 Fasteners get their strength and corrosion resistance from the material composition. There are austenitic and ferritic steel phases in the metallurgic microstructure of the Super Duplex 2507 Bolts and other fasteners. So they can withstand high corrosion without compromising the high strength as well. The specification for the UNS S32750 Bolts and fasteners is the ASTM SA790. The specification covers fasteners for high temperature and pressure applications. The sizes range from M02 to M30. The length of the UNS S32760 Stud Bolts range from 2mm to 200mm. There are different grades within this super duplex material such as S31803, S32507 and so on depending on the compositional difference. The UNS S32760 Fg Stud Bolts and other fasteners also have high strength values.

12 point screws are used in applications where the screws have to be driven hard and tight. The grip on the head is maximized through the shape. Viha Steel & Forging is a leading manufacturer and supplier of the different 12 point screws stainless steel in different grades. The head of the screw has twelve points as an overlap of two hexagons. The screws also have a flanged underside. The stainless steel 12 point flange screw is also called the ferry cap screws. The point sizes range from ¼ inches to 4 inches and M6 to M100. There are different specifications to cover different sets of applications such as IFL-115, MIL SPEC, DIN 34822 and DIN 34821. The metric 12 point screws have great torque capacities that exceed the socket head screws and the cap screws. The head of these screws is small compared to hex head screws. Therefore these 12 point cap screws are used in tight space applications where the space and weight are critical.

En 14399-4 Bolt is made up of medium carbon alloy steel, medium carbon steel or low carbon steel materials. Viha Steel & Forging is a leading manufacturer and supplier of the different types such as the En 14399-4 Hv Bolts which are heavy bolts. These are used in preload assemblies, so the strength and corrosion resistance of all the bolts in the assembly have to be compatible. The En 14399-4 Hex Bolt is mostly made up of a property class 10.9 steel material. These bolts exhibit good wear resistance as well. The Din En 14399 4 Bolt has some of the very high strength values. The minimum yield strength of the bolts is around 940MPa and the minimum tensile strength is around 1040MPa. The Din 6914 En 14399-4 Bolts are of high tensile strength so that they can handle much greater loads compared to the other bolt types. 

dti washer manufacturers produce these direct tension indicator washers in different material grades and sizes. Viha Steel & Forging is a leading manufacturer and supplier of the direct tension indicator washers in large quantities. There are two main types of direct tension indicator washers. The traditional DTI get the pumps around the washer flattened with the proper tension. The DTI squirters will give out a colored silicon content that confirm the proper tension achieved by the direct tension indicators astm f959. The DTI washers give the installer a confirmation of the proper torque or tension achievement. The applications such as construction sites, larger load bearing assemblies and others use the astm f959 dti washers for confirmation of the correct fitting of heavy bolts that are often of high tensile strength. The washers vary in size accommodating small to large scale bolts and nuts.

Grade 12.9 Bolt belongs to the ASTM F568 specification. And the specification has bolts, screws and other fasteners. Viha Steel & Forging is a leading manufacturer and supplier of the Class 12.9 Bolts in different dimensions. The size ranges from M1.6 to M100. The bolts are stronger and corrosion resistant. The class 12.9 Hex Head Bolts are made from this material with 1220MPa minimum tensile strength. So the Yfs 012.9 Bolt is quenched and tempered to get this kind of high tensile strength. Due to this reason, the high tensile bolts 12.9 grade are also known as high tensile bolts. The high tensile bolts are needed for applications with high tensile strength requirements such as bridges, construction sites, engineering applications, piping and others.

A193 B6 Studs are some of the fasteners specified for the high tensile applications. There are bolts, stud bolts, threaded rods and other types of fasteners with external threads. Viha Steel & Forging is a leading manufacturer of the ASTM A193 Grade B6 Bolts. These fasteners are made up of AISI 410 stainless steel grade material. The material is heat treated to make the bolts with 110ksi minimum tensile strength. The ASTM A193 B6 Stud Bolts have carbon, manganese, phosphorus, sulfur, silicon and 11.5% - 13.5% chromium. The material is heat treated, quenched and tempered to 593 degree Celsius.  The material grade includes fasteners with diameters up to M100. The Sa193 Gr B6 fasteners have minimum 760MPa tensile strength and 585MPa minimum yield strength. The elongation is 15% and the hardness varies. The fasteners of the Asme Sa 193 B6 have excellent corrosion resistance, dimensional stability, strength, durability and long lasting life.

ASTM A193 Grade B6x Stud bolts are high tensile material made bolts. The fasteners belong to the specification that has high temperature, high corrosion resistant, external threaded fasteners. Viha Steel & Forging is a leading manufacturer and supplier of the different types of fasteners such as the ASTM A193 B6x Threaded Rod and others. The material has carbon, manganese, phosphorus, sulfur, silicon and 11.5% to 13.5% chromium in the composition. The material composition makes the material strong and corrosion resistant. The minimum tensile strength of the ASTM A193 Grade B6x Hex Bolt and other fasteners is 620MPa. The hex bolts are used in different applications due to the shape and use with tools. The ASTM A193 Grade B6x Bolts have 485MPa minimum yield strength, 16% elongation and 26HRC hardness. The material is heat treated similar to the B6 fasteners. 

ASTM A193 Grade B8 Class 2 Bolts are high strength fasteners that are used in various industrial applications. Viha Steel & Forging is a leading manufacturer of the different types of the B8 fasteners. There are two classes. The Astm A193 B8 Class 2 Bolts are strain hardened and are used in high stress applications such as petroleum, oil and gas, chemical and construction applications. The fasteners are made up of 304 austenitic stainless steel grade material. The B8 Class 2 Stud and other fasteners have minimum tensile strength ranging from 75ksi to 125ksi depending on the different sizes. The smaller sizes usually have high strength. The astm a193 b8 class 2 torque chart provides the different strength and capacities of different types, shapes and sizes of the different fasteners in this grade. There are different types such as threaded rods, screws, washers and others. The ASTM A193 B8 Cl2 has good general corrosion resistance.
