Alloy details-
Alloy 321H is the stainless steel austenitic alloy that is titanium stabilized and is known popularly for its general corrosion-resistant ability. This grade is the high carbon version of 321 stainless steel alloy that is offering very good oxidation-resistant ability at temperature 816 deg C. Also it is having very good low-temperature toughness. It too has good machinability and corrosion-resistant ability. It can be welded readily through the standard welding process. The alloy is ductile and it forms easily. Thus this alloy is extensively used in many industrial applications.

Manufacturing of the stainless steel bars-
At our highly operational manufacturing unit, the production of AISI 321H Stainless steel round bars is done using the superior quality of alloy. The alloy that is used for the fabrication of these bars is collected from the reliable market mills and is well tested once bought into the industry. Using the pure quality of alloy adds greater strength to the product quality. We at the time of product development are making the use of sophisticated technology and latest technology that develops the bars assuring fine finishes and perfection in dimensional accuracy. We are having a team of experts that are looking at the effectiveness of the development of the bar. They are guiding the workers at all levels of product development for making sure that no poor quality of bars production could exist. The quality checker team efforts in quality examining have helped us in the supplying and exporting of the superior quality of bars. All offered ranges of bars are developed according to the set manufacturing norms and product quality standards.

Bars properties-
Among the numbers of industries, our manufactured and offered ranges of AISI 321H Stainless steel round bars are highly appreciated. Therefore it is widely used in ranges of applications in industries. Some properties found is including-
• High tensile strength
• Good dimensional accuracy

Testing of the bars-
We before doing the delivering of the bars to the buyers are conducting the quality checking of the product. This is essential as through it we can easily do the identification of the quality of the bar. Testing doesn’t allow us to deliver poor quality of bars. The tests that we conduct are positive material identification test, mechanical test, chemical test, intergranular corrosion test, pitting resistance test, macro test, micro test, hardness test, etc.

Documenting-
We are offering copies of the certain documents to the buyers. Those are heat treatment chart, packaging list, commercial invoice, guarantee letter, QAP, raw material test report, material traceability report, NABL approved lab test report. Also, we are providing MTC as per EN 10204/3.1b, 100% radiography test report, third party inspection report, raw material certificate, buyers report, etc.

Packaging-
For damage-free shipping of the AISI 321H Stainless steel round bars, the packaging we conduct is in plywood boxes and as per clients requests.

What is the chemical composition of 321h Stainless Steel round bar?

321h Stainless Steel round bar is a type of stainless steel designed for use in high temperatures, boasting excellent corrosion and oxidation resistance. This alloy comprises both chromium and nickel, typically 18%-20% chromium and 8%-12% nickel, alongside 2%-3% titanium. 321h also contains carbon, silicon, manganese and phosphorus but only in trace amounts. As 321h Stainless Steel has good weldability, it's often used for industrial purposes such as manufacturing machinery elements, equipment parts and fuel cell components, making it an invaluable material worldwide.

What is the difference between stainless steel 321 and 321H rod?

321 and 321H stainless steel rods differ in their carbon content. 321 contains about 0.08% carbon, while 321H includes between 0.04–0.10% carbon by weight. The higher levels of carbon in 321H make it more susceptible to intergranular corrosion if heated to high temperatures, making 321H better suited for high-temperature applications like specialized furnaces or chemical processing equipment due to its greater resistance to creep deformation than 321. In contrast, 321 is a better option for general use due to its higher resistance to sensitization and general corrosion properties than 321H. Choosing the right type of stainless steel rod for the application at hand – 321 or 321H – is important based on your project requirements and needs.
