As a highly acclaimed industry we Piyush Steel is engaged in manufacturing and providing the comprehensive ranges of high quality of AISI 446 stainless steel round bars. We today are dealing at a greater extent as a manufacturer, supplier, and exporter of the round bars. Due to many good features that are found in the bars, the demand and usability of it has got increased a lot. The application wherein bars are used is chemical atmosphere, flue gas desulfurization, etc. All our esteem patrons whether global or local can avail these bars from us at various specifications. It thus varies in standards, dimensions, outer diameter, types, lengths, forms, and surface finishes. These bars that are also known as UNS S44600 or WNR 1.4006 bars can also be availed at cut-made specification exactly as per the demands made by the clientele.

Stainless steel 446 is the high chromium ferrite heat resistant grade that is having very good sulfidation, oxidation and other hot corrosion form resistant. Though the elevated temperature strength of the alloy is low, this alloy is used commonly in between the temperature ranging 1500 to 2100 Deg F. This grade is heat resistant alloy that tolerates the molten brass and copper. With the other high chromium ferritic stainless, 446 is embrittling severely in temperature ranging 700 to 1000 Deg F. 446 shouldn’t be used in the temperature ranges unless the complete loss of room temperature ductility might be tolerated. Sigma phase embrittlement occurs in a long-time exposure to the temperature 1000 to 1300 def F range. 446 SS is having high ductile to the brittle transition temperature. The successful bending and aiding are aided by the edge preparation, low forming speed and preheating at the temperature ranging 250 to 400 deg F. Annealing when needed must be performed at the temperature ranging 1550 to 1650 deg F followed by rapid cooling. Welding can be done through conventional techniques. Post heating and preheating to 300 to 600 deg F is helpful. Austenitic weld filler like AWS E310 or E321 is suggested for maximizing the weld deposit ductility.
Because of some properties found in the AISI 446 stainless steel round bars that we had manufactured and is offering to the buyers had become high in demand. This product has become an ideal choice for various applications and is thus used in many industrial applications. The qualities found in it is-
• Rugged construction
• Pitting/oxidation resistance
• General corrosion resistance

• Long working ability
The manufacturing of AISI 446 stainless steel round bars is conducted under the proper supervision of professional experts. The proper guidance of these experts helps us in the development of the premium of alloy. At the time of product development, we are using the superior quality of alloy in addition to refined technology and modern tools. The bars that we are offering are developed according to the set manufacturing norms and raw material quality standards. The quality control team sincere efforts toward product quality checking have helped us in making and providing the best possible quality of bars.
The testing of AISI 446 stainless steel round bars before its delivering to the buyers are done to check its quality. The tests done are like-
• Positive material identification test
• Hardness test
• Flattening test
• Flaring test
• Macro test
• Micro test
• Intergranular corrosion test
• Pitting resistance test
To deliver bars without causing damages, its packaging is done carefully like in wooden boxes, wrapping in plastic sheets or as per clients demands.
