Stainless steel 316 round bar

Stainless Steel 316 Round Bar Specifications

How does the corrosion resistance of Stainless Steel 316 Flat Bar, Hex Bar, and Square Bar compare to Stainless Steel 304?

This resilient grade comprises additional 2% molybdenum to enhance its chromium-nickel alloying composition. Hence, a stainless steel 316 flat bar exhibits superior corrosion resistance over 304, with a higher PREN (Pitting Resistance Equivalent) of 24.2 over 19.

These products also show higher creep resistance at elevated temperatures and have widespread industrial, structural, and marine applications. A stainless steel 316 flat bar can handle sulfuric acid up to 5 per cent, 20% phosphoric acid, and fatty acids. However, it suffers when exposed to concentrated nitric acid and faces carbides precipitation in the 800 to 1500°F range. Still, a stainless steel 316 hex bar resists stress-corrosion cracking better than 304.

How do you ensure the accuracy of cutting, drilling and bending services for a Stainless Steel 316 Flat Bar/Hex Bar/Square Bar?

These are standard fabrication and forming techniques for an ASME SA 240 316 stainless square bar. Using sharp and compatible cutting tools and guaranteeing quality adherence is vital for long-term performance. Automated, CNC-controlled, or laser-led cutting at suitable speeds are best for a stainless steel 316 hexagon bar.

Thorough quality control involving visual inspection and NDT/manipulative testing is paramount for a WNR 1.4401 SS 316 ring. For instance, we recommend flattening tests, tensile strength assessment, and ultrasonic examination to diagnose defects and discontinuities.

What is the average price range for Stainless Steel 316 Hex Bar in the market?

Buyers will find an ASTM A240 WNR 1.4401 SS 316 flat bar more expensive than its 304 counterparts. The superior metallurgical characteristics hike the price to around Rs 416 per kilogram for up to 2 inches in diameter and 6m in length.

A polished 316 stainless steel flat bar costs considerably more because of the additional processing and higher lead times.

The cost of an SS 316 square bar depends on the quality of the raw materials and the global demand-supply situation. Manufacturers boasting tighter tolerances and quality standards quote steeper rates for ASTM A240 UNS 316Ti SS circle.
