Grade 8.8 is an exceptional grade of steel capable of carrying a great tensile load while at the same time retaining its versatility. This is the reason why grade 8.8 steel is a very popular material and widely used across different industries. Grade 8.8 Bolts are made from medium carbon steel which has undergone a quenching & tempering process. Due to its strength and versatility grade 8.8 is still considered the most common steel bolt grade used in construction. Grade 8.8 bolts are used in a wide range of applications such as bridges, high-rise buildings and other infrastructural projects. Steel beams and columns are fixed using Grade 8.8 bolts. Motor vehicles, where the chassis and suspension systems are primarily the components to be bolted with Grade 8.8 bolts. These parts experience very high dynamic loads and therefore require very strong fasteners. Machinery and equipment, Grade 8.8 bolts are used in heavy machinery and industrial equipments due to their strength.
Grade 10.9 is a high tensile grade bolt, typically made from carbon steels and low boron steels materials. After the heat treatment those materials reach the hardness, strength and other mechanical properties that are required for Grade 10.9 Bolts. A Grade 10.9 bolt finds its use in engine components and suspension systems. The main functions of bolts in engine assemblies are to load the bolts with high temperatures and vibrations. Furthermore work with an aluminum engine block requires additional care of gums galvanic corrosion and thread stripping. Grade 10.9 bolts are extensively used in structural work to connect steel girders and other components. If you are in search of tough and reliable bolts and nuts that are many times more durable than ordinary and at locations such as Peru, Chile, Brazil, Argentina and whole South America etc., you should think of Vision Alloys which is a market leading company in this area.
