Stainless steel 316L Black Bar is an alloy made up of iron, chromium, nickel, molybdenum and small amounts of carbon. It is also suitable for lower temperatures because its low carbon content prevents carbide precipitation. Its weldability makes it a preferred choice for many structural products, such as flooring grates or handrails. In the past several decades, 316L ss Black Bars have become increasingly popular due to their versatility and affordability.
SS 316L Forge Bar is an iron-based alloy containing chromium, nickel, and molybdenum. It has a higher level of corrosion resistance than 304 grade due to adding 2-3% molybdenum. This provides excellent resistance to acidic and alkaline environments and elevated temperatures up to 1,000°F (537°C). This alloy is commonly used for cryogenic applications and medical implants due to its excellent formability and weldability. Its history dates back to World War II when it was created by Allied forces in order to make weapons with superior corrosion resistance compared to traditional carbon steel alloys. Today, grade 316L Forge Bar remains one of the most popular alloys for industrial applications around the world.
Corrosion Resistance 316L Black Bars
316L Black Bars are extremely corrosion resistant due to their low carbon content. SS UNS S31603 contains a high level of molybdenum which makes it highly resistive against chloride environments and helps to protect against pitting, crevice corrosion, and general corrosion. The black finish also adds another layer of protection by reducing contact with oxygen, slowing down oxidation and extending product life.
Machining 316L Black Bars
Machining stainless steel 316L Black Bars require expertise and precision to produce a high-quality product. Typically, 316L stainless steel bar is pre-drilled on one end before machining begins. To reduce friction, lubricants such as cutting oils or coolants are applied. The machined surface is inspected for quality before being heat treated if required. Machining on UNS S31603 black bars should be done with carbide tools with low cutting speeds and multiple passes depending on the material’s thickness, hardness, and size.
Chemical Features 316L Black Bars
ss 316L Black Bars are manufactured using a low-carbon stainless steel alloy known for its superior corrosion resistance properties. These bars are typically cold drawn and have excellent mechanical properties, including excellent tensile strength, stress corrosion cracking resistance, and hardness. Additionally, they provide great weldability and make them suitable for use in harsh environments such as high-temperature applications. The black oxide finish also increases the bars' wear resistance to improve longevity.
Uses 316L Black Bars
316L stainless steel Black Bars are a metal bars made from high-alloy austenitic stainless steel with superior corrosion resistance and durability, making them ideal for industrial applications such as machine frames, rotating machinery components, medical implants, marine hardware and more. They offer excellent weldability while providing comfort to the user due to their non-magnetic properties.
