316L Stainless Steel

316L stainless steel is an important member of the austenitic stainless steel family and is known as the “king of corrosion resistance” for its excellent corrosion resistance. It is made by adding molybdenum to 304 stainless steel. The molybdenum element improves the resistance of 316L SS steel to pitting corrosion, crevice corrosion, and stress corrosion cracking. It is widely used in marine, chemical, and medical fields.

Wanzhi Steel is a professional Chinese manufacturer of 316 and 316L steel products. We produce 316 and 316L steel coils, sheets, pipes, wires, and cables, and offer custom sizing as well as OEM services.

Mechanical Surface Treatment of 316L

• Polishing: High aesthetics, easy to clean.
• Brushing: Silky texture, wear-resistant, providing a low-key and simple feel.
• Sandblasting: Matt surface, improves coating adhesion.
• Embossing: Increases friction for decoration.
• Mirror: 8K, 10K, 12K, etc. The larger the number, the better the mirror effect.
• Etching: Combination of glossy and frosted surfaces, background walls, and bar facades.
• Electroplating: Multiple colors, creating a sense of luxury.

Mirror polishing grades

The mirror polishing grades of 316L stainless steel are differentiated according to the surface roughness (Ra value) and glossiness.

• BA (Bright Annealed) surface: roughness 0.05-0.1 μm.
• No.4 (Hairline) surface: roughness 0.2-0.4 μm.
• No.6 (Fine Satin) surface: roughness 0.1-0.2 μm.
• No.8 (Mirror) surface: roughness ≤0.05 μm.
• Super Mirror surface: roughness ≤0.01 μm.

Characteristics of 316L stainless steel

• Excellent corrosion resistance: Good corrosion resistance in both oxidizing and reducing media, especially resistance to pitting, crevice corrosion, and stress corrosion cracking.
• Good processing performance: Easy to perform hot and cold processing and excellent weldability. The high temperature resistance limit is 1575℃ and the minimum is 800℃.
• Excellent low temperature performance: Low-temperature resistance, the lowest can reach minus 196℃, and it can still maintain good toughness and plasticity in low temperature environments.
• Non-magnetic: Suitable for applications sensitive to magnetism.
• Good biocompatibility: Widely used in medical devices and human implants.

Price of 316L stainless steel

The price of 316L stainless steel is affected by many factors, including raw material prices, market supply and demand, processing technology, etc.

Generally speaking, the price of 316L stainless steel is higher than that of 304 stainless steel but lower than some special stainless steels.

For specific prices, please get in touch with our professional technicians with product specifications for consultation.

316L stainless steel production process

Scrap steel and ferroalloys are melted in proportion→Refining with AOD or VOD (to reduce carbon and gas content) →Molten steel is cast into billets→Hot rolling→Cold rolling→Annealing→Pickling→Polishing etc.→Quality inspection→Packaging→labeling→Storage

Is 316L the same as 316 stainless steel?

The two are different. Although the names are similar, they are different in performance and purpose.

1. Performance

• Carbon content: 316 carbon content ≤0.08%, 316L: carbon content ≤0.03% (low carbon),
• Corrosion resistance: 316L is better than 316, especially after welding.
• Weldability: 316L is better than 316, no annealing is required after welding.
• Strength: 316 is higher than 316L because its carbon content is slightly higher.

2. Uses

In contrast, 316 stainless steel is suitable for general corrosion, and 316L stainless steel is suitable for more severe corrosion environments, especially where welding is required.
