20MM T303 Stainless Round
$29.66 – $154.15
Metric bearing quality T303 stainless round bars are great for bearing shaft or metric applications. Also known as “free-machining” stainless, T303 has good non-seizing properties and is the most machinable of the chromium-nickel stainless grades. T303 has excellent corrosion resistance, but less than other grades such as T304 or T316. Its tensile strength and hardness can be increased by cold working. Slight magnetism can be detected by cold working.
|Ultimate Tensile Strength||85,000-95,000|
|Machinability and Weldability
Machinability is rated at 78% of B1112. Average cutting speed 130 ft/min. 303 has only low to fair welding properties. 303 can be forged between 2100Â°-2350Â° F. Do not forge below 1700Â° F.
