ASTM A276 grade 316 round bar

Table of Content

What is an ASTM A276 Grade 316 round bar?

These products adhere to the specification for hot-finished and cold-finished bars made from Grade 316 stainless steel. An ASTM A276 Grade 316 round bar is highly corrosion resistant due to the molybdenum (~3%) in its chromium-nickel profile. This round bar handles saltwater (chlorides) in marine applications and resists pitting in pharmaceuticals.

What is the ASTM A276 Type 316 Forged Bar size range? Which size is commonly used?

A forged bar comes in multiple sizes, but standard lengths are 2000 to 6000 mm. Clients can purchase an ASTM A276 Type 316 forged bar in diameters of 3 to 800 mm (round). Thicknesses of 2 to 100 mm are regular for flat bars. You may order custom sizes for a cold drawn round bar.

What are the testing methods of an ASTM A276 316 square bar?

These bars undergo macro/micro testing using destructive and NDT techniques. An A276 Grade 316 polished bar gets subjected to Charpy impact tests, magnetic particle inspection, and corrosion testing.

Manufacturers also use radiography for the composition of a threaded bar. Finally, ultrasonic testing diagnoses defects in a cold rolled bar. The MTC of the bars reflects these results. At the client’s discretion, a third-party inspection or lab testing for a rectangular bars may be conducted.

What is the application of an SA 276 gr 316 Cold Drawn Round Bar?

Strength and corrosion resistance ready an SA 276 gr 316 cold drawn round bar for hydraulic applications, oil and gas production, and petrochemicals. An ASTM A276 Grade 316 cold rolled bar also works in shipbuilding and construction.

What is the difference between ASTM A276 316 condition A vs. condition B?

Condition A in an SA 276 Grade 316 threaded bar refers to the annealed state, which improves the ductility of the hot rolled bars. But Condition B involves heavy cold work for greater strengthin an ASTM A276 316 hot rolled bar. It includes ageing and double ageing for the rounds.

How is the surface finish of an ASTM A276 UNS S30400 Rod achieved?

Surface finishes for an ASTM A276 UNS S30400 rod include peeled, bright, rough-turned, and polished. Mills use fabrication, priming, etc., to prepare an SA 276 316 black bar. Other techniques for a polished bars are galvanising (zinc dip), powder coating, and painting. Thermal spraying also works for a rod.
