Introduction

321 321H Stainless Steel Bar is titanium stabilized stainless steel grade from the austenitic family. It has the higher corrosion resistance ability and phenomenal resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range in temperature up to 427 deg C to 816 deg C. it has excellent oxidation resistance to 1500 deg F. moreover, it is known for higher stress to rupture and creep strength. 321 alloys have good low temperature properties and toughness.

321 321H Stainless Steel Bar has a higher carbon content of about 0.04 to 0.10%. It is developed to offer resistance to creep and higher strength up to 537 deg C. in most cases alloy meets the dual certification. SS 321H alloy can only be hardened by cold working operations, not by heat treatment operation. It is effectively welded and manufactured by standards machines.

Features

The surface of the product is smooth. The high-pressure water descaling process is used twice in the process to ensure the surface of the steel is smooth and clean .

The sides are vertical, and the rhomboids are clear. The two vertical rollings in finishing rolling ensure good verticality on both sides, clear corners, and good surface quality on the sides.

The scale of the product is accurate, three points difference, the same level difference is better than the steel plate standard; the product is straight and the shape is good. Finishing rolling adopts continuous rolling process and automatic looper automatic control to ensure that no steel is piled or pulled. The product has high dimensional accuracy. The tolerance range, three point difference, same strip difference, sickle bend and other parameters are better than the medium plate, and the shape Good degree. Cold-shear cutting, high precision in length sizing.

The product material adopts national standards and is the same as steel plate. The quality and technical standards are organized according to YB / T4212-2010 standards (Q345B / Q235B refer to GB / T1591-94 and GB / T700-06 standards, respectively).

Application

Flat bar is rolled with negative deviation, but it is delivered according to actual weight, and the utilization rate is increased by 1 to 5 percentage points compared to steel plate.

Flat steel can be produced according to user requirements in fixed thickness, fixed width, and fixed length, which reduces cutting for users, saves processes, reduces labor and material consumption, and also reduces processing loss of raw materials. material. The products have been professionally used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, lifting machinery and other industrial materials.
