Bhawal Steel Agency is a manufacturer, supplier, stockist, and exporter of all types of steel products. We manufacture products using superior quality products. There are several types of stainless steel pipes available in the markets. These pipes are obtainable in different dimensions, shapes, and sizes.

Grade 304H is also known as 18/8 austenitic stainless steel. It is called 18/8 because of its chemical composition which includes 8% nickel and 18% chromium. These stainless steel 304H pipes are commonly being used in massive industries. These stainless steel pipes are surprisingly used for heavy fabrication and other purposes because of their high carbon content. Bhawal Steel Agency is the most reliable steel manufacturing industry that produces various types of products. We manufacture these stainless steel pipes using excellent quality raw material which is thoroughly tested and approved by experts.

These pipes are also called a mixture of ferrite and genuine steel. Which provides high elasticity to the grade. These stainless steel 304H pipes are created using unmatched material to utilize them.  This grade is enriched with excellent bendability and moldability; hence it is often applicable where chloride is being used.

Stainless steel 304H pipes are enhanced with excellent ductility and malleability. It has the ability to bear the high heat and extremely bad weather conditions. These pipes are commonly used for transmitting fluids, liquids, acids, and gases from one place to another. It can easily transfer deadly acids and seawater without facing any damage. Stainless steel 304H pipes have high heat tolerance and durability. It’s tensile and yield strength are analogously higher than other stainless steel grades. These stainless steel 304H pipes are applicable in various industries because of their chemical and mechanical properties. These 304H pipes are applicable in petrochemical industries, paper and pulp making industries, petrochemical industries, etc.
