Triroundbars.com is one of the largest exporters, manufacturers and suppliers of Stainless Steel 321H Round Bars in India. Our 321H Stainless Steel Bars are a modification of SS 321 with a higher carbon content, to provide improved high temperature strength. Also known as UNS S32109 Bars, these 321H Stainless Steel bars are used for several applications such as in the Aircraft industry, Heat exchangers, Fabrication industry, Refinery industry equipment, Oil refineries, High temperature chemical process equipment, and more.

ASTM A276 321h Round Bar can be categorically said that steel bars are one of the core components of any manufacturing industry or for that matter any industry that relies on machineries. versatile applications in automotive, textile, fabrication, construction, cement, ship building, paper and pulp, defence, heavy earth moving equipment or aerospace.

Grade 321h Stainless Steel is designed for high temperature service, combining excellent high temperature properties with good ductility and weldability. Providing reduced sulphur gases are not present, it resists oxidation in continuous service at temperatures up to 1150°C. It can also be used intermittently at temperatures up to 1040°C.

The UNS S321h08 grade is used when moisture and corrodes are present in an application environment that is lower than normal

Triroundbars.com Inc.s are Recognized as the Prominent Manufacturer, Exporter and Supplier of a broad assortment of ASTM A276 321h Round Bar. The offered ASTM A276 321h Round Bar is designed with utmost precision in conformity with the international quality standards.

Like other austenitic grades, these have excellent toughness, even down to cwet corrosion in a lower temperature range of this environment.

It is a 0.03% maximum carbon version of 321h, sometimes used for very specific corrosive environments, such as urea production.

Electric arc welding is one of the oldest processes for joining metals, and it is widely used across the globe. It is generally known as MMA (manual metal arc welding). In steel and pipeline construction, electric arc welding with stick electrodes is still indispensable, as it can be performed in any weather condition. Around 30 to 35% of the world’s welded products are produced with this method.

Triroundbars.com produces high-Quality stainless steel bars in an industry-leading variety of grades and shapes. High-performance stainless steel bars are available in a wide range of grades. If you want superior machinability, faster machine speed, longer tool life, and superior performance in terms of tolerance and surface, choose our range of products.

Alloy details

A popular corrosion-resistant alloy, alloy 321H is a stainless steel austenitic alloy stabilised with titanium. The high carbon version of 321 stainless steel alloy offers excellent corrosion resistance at 816 degrees C. It is also very tough at low temperatures. Machinable and corrosion-resistant. It can be welded using standard techniques. It is ductile and easily formed. This alloy is widely used in a variety of industrial applications.

Manufacturing of the stainless steel bars

AISI 321H stainless steel round bars are produced in our highly operational manufacturing unit using superior alloy quality. The alloy that is used for the fabrication of these bars is collected from the reliable Once bought into the industry, it is well tested. 

Tin alloy gives greater strength to this product and at the time of product development, we are using the latest technology to develop the bars assuring fine finishes and precision in dimensional accuracy. A team of experts is examining the effectiveness of the development of the bar.

At all stages of product development, they ensure that the bar production is of the highest quality. As a result of the quality checker team’s efforts, we have been able to provide and export superior quality bars. The bars that are offered are developed according to the set manufacturing norms and product quality standards.

Bars properties

Our AISI 321H Stainless steel round bars are highly acclaimed in a variety of industries. Because of this, they are widely used in a variety of industries. Some of their properties include:

• High tensile strength
• Good dimensional accuracy
• Fine surface finishes
• Longevity
• Anti-corrosive body
• Good mechanical strength
• General corrosion resistance
• Holds high heat
• Rust free

Testing of the bars

They conduct a quality check of the bars before delivering them to the buyers. In this way, we can easily identify the quality of the bar. Testing doesn’t allow us to deliver poor quality 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

The buyers can purchase copies of certain documents. Heat treatment chart, packaging list, commercial invoice, guarantee letter, QAP, raw material test report, material traceability report, and NABL lab test report. In addition, we provide 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, we pack them in plywood boxes and according to client requests.
