About Stainless Steel 304/304L/304H Buttweld Fittings

Stainless Steel 304/304L/304H buttweld fittings are the piping industry’s most widely used and versatile grades of stainless steel. Each grade offers different mechanical and chemical properties suited for specific applications.

Stainless Steel 304 is the standard “18/8” stainless steel and is the most widely used grade for buttweld fittings. It has excellent forming and welding properties and good corrosion resistance, making it ideal for many applications. Stainless Steel 304L is a low-carbon version of 304, making it resistant to intergranular corrosion and suitable for use in the as-welded condition. It is commonly used in applications where the environment is highly corrosive and where post-weld annealing is not possible.

Stainless Steel 304H is a high-carbon version of 304 designed for high-temperature applications. It offers superior strength and durability compared to 304 and 304L, making it ideal for applications with high-temperature resistance. In terms of mechanical properties, Stainless Steel 304 has a yield strength of 205 MPa and a tensile strength of 515 MPa, while 304L has a yield strength of 170 MPa and a tensile strength of 485 MPa. 304H has a yield strength of 205 MPa and a tensile strength of 515 MPa, making it the strongest of the three grades.

Stainless Steel 304/304L/304H buttweld fittings are a versatile and reliable option for many applications. Each grade offers different mechanical and chemical properties suited for specific applications, making it essential to choose the right grade for your needs.

Our company packs Stainless Steel 304/304L/304H buttweld fittings with the utmost care to ensure safe and secure transportation. Each fitting is thoroughly cleaned to remove debris or contaminants and then carefully wrapped in protective material to prevent damage during transit. The fittings are packaged in sturdy wooden boxes or crates, labeled with relevant information such as product specifications, grades, and quantities. This helps keep the fittings in good condition and makes it easier to identify and track the products during transit. Our packing methods ensure that the fittings reach the customer in perfect condition and ready for use.
