What is ASTM B348 Grade 2 Grade / Grade 5 ?

The ASTM B348 Grade 2 Fasteners have great resistance towards corrosion. Also, they possess the property of being weldable as well as formable. This is why they are used in a large number of critical applications. Whereas, the Grade 5 Fasteners are called alpha beta alloy because they have the similar characteristics like pure titanium. These include low density as well as high strength.

The Grade 2 fasteners are stronger as compared to the grade 1 fasteners however they almost have equal resistance towards corrosion. These are used in applications such as heat exchangers. The alloy with Grade 5 fasteners possesses the property of stability and therefore they can undergo the hot working process. The hardness of the alloy can be improved by adding aluminum to the alloy. Alloying provides extra benefits to the fasteners and gives beneficial properties such as improved tensile strength.



Sumit Impex is well-known for manufacturing high-quality ASTM B348 Grade 2 Grade / Grade 5 Fasteners. In order to produce a high-quality product, they adhere to all standards and procedures, as well as industrial norms and guidelines.

Because of the properties as well as the characteristics that these fasteners have they are used in a large number of industrial applications. These include chemical industries, aerospace, marine industries, etc.
