What are “steel” and “iron”? What are their characteristics and relations? How do the 304, 304L, 316, and 316L seen in ordinary times come from? What’s the difference between them?
Steel: A material consisting mainly of iron, generally containing less than 2% carbon, and containing other elements.
Iron: Metallic element, atomic number 26. Iron materials are ferromagnetic and have good plasticity and thermal conductivity.
Stainless steel: air, steam, water, and other weak corrosive medium or stainless steel. Usually used for 304, 304L, 316, 316L, is austenitic stainless steel 300 series of steel.
What is the best grade of stainless steel for jewelry?
316L stainless steel is best for jewelry. The most common grade used for stainless steel jewelry is 304 (18-20% chromium and 8-10.5% nickel). while better Jewelry brands use the hypoallergenic grade 316, 316L, and 316F, with extra 2-3% molybdenum for better resistance to corrosives.
What is the difference between 304L and 304?
The only difference between them is the carbon content; the 304 stainless steel has a maximum range of carbon of 0.08% whereas the 304L has a maximum range of 0.03%. This range of carbon in the steel affects the corrosion resistance of the tanks. … The change from 304 to 304L was made 20 years ago.
304 STAINLESS STEEL
Is 304 stainless steel jewelry safe?
Stainless steel jewelry that is made like medical-grade stainless steel is perfectly safe to wear. An example would be 316L or 304 stainless steel.
- 304 STAINLESS STEEL PERFORMANCE IS INTRODUCED
304 stainless steel is the most common, as a widely used steel, with good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties. Stamping, bending, and other heat processing good, no heat treatment hardening phenomenon (no magnetic, then use temperature -196℃ ~ 800℃).
- 304 STAINLESS STEEL SCOPE OF APPLICATION
Household items (1, 2 types of tableware, cabinets, indoor plumbing, water heater, boiler, bathtub). Auto parts (windshield wipers, mufflers, molds). Medical equipment, building materials, chemistry, food industry, agriculture, ship parts, etc.
304L STAINLESS STEEL (L IS LOW CARBON)
- 304L STAINLESS STEEL PERFORMANCE IS INTRODUCED
Most importantly, as a low carbon 304 steel, its corrosion resistance is similar to that of 304 steel in general conditions. After welding or stress relief, it has excellent resistance to grain boundary corrosion. It can maintain good corrosion resistance without heat treatment at temperatures from -196°C to 800°C.
- 304L STAINLESS STEEL SCOPE OF APPLICATION
Open field machines for chemical, coal, and petroleum industries with high requirements for corrosion resistance at the grain boundary, heat-resistant parts of building materials, and parts with difficulty in heat treatment.
316L vs 316 Stainless Steel
Is 316 better than 316L (difference between 316 and 316l)?
316L is the superior choice for high corrosion and high-temperature applications. The key difference between 316 and 316L stainless steel is the carbon content. While 316 has a maximum carbon content of 0.08%, 316L has a maximum carbon content of only 0.03%. Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, meaning its welds won’t decay, unlike with 316 stainless steel.
316 STAINLESS STEEL
- 316 STAINLESS STEEL PERFORMANCE IS INTRODUCED
316 stainless steel has added molybdenum. Its points are corrosion resistance, atmospheric corrosion resistance, and high-temperature strength. That is to say, it can be used in harsh conditions. Work hardening excellent (non – magnetic).
- 316 STAINLESS STEEL SCOPE OF APPLICATION
Seawater equipment, chemical, dyestuff, papermaking, oxalic acid, fertilizer, and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.
What does the L stand for in 316L stainless steel?
Stainless Steel 316 L is also known as ‘Marine Grade’ Stainless Steel. … Where does the L stand for in 316L? The letter itself stands for Low (meaning Low carbon) L grades have 0.03% carbon maximum. L grades are resistant to sensitization in short-term exposures or heat treatments.
- 316L Stainless Steel PERFORMANCE IS INTRODUCED
As a kind of 316 steel, the low carbon series has the same characteristics as 316 steel and has excellent corrosion resistance to the grain boundary.
- 316L Stainless Steel SCOPE OF APPLICATION
Products with special requirements against grain boundary corrosion.
- 316L Stainless Steel THE PERFORMANCE COMPARISON
Chemical composition. 316 and 316L stainless steels fall into the category of molybdenum-containing stainless steels. The molybdenum content in 316L stainless steel is slightly higher than that of 316 stainless steel. However, due to the presence of molybdenum in the steel, its overall performance is better than 310 and 304 stainless steel. Moreover, under high-temperature conditions, 316 stainless steel has a wide range of USES when the sulfuric acid concentration is below 15% and above 85%.
316 stainless steel also has good chloride attack properties. It is commonly used in marine environments. 316L stainless steel has a maximum carbon content of 0.03. Moreover, it can be used where maximum corrosion resistance is required. Based on all the factors, I think the best choice of jewelry material is 316L stainless steel. It has excellent corrosion resistance, heat resistance, welding, and mechanical properties. Low carbon stainless steel – 316L stainless steel is the best choice.
316L Stainless Steel Jewelry’s Advantage
316l stainless steel jewelry color with ion plating, colors will not fade and anti-tarnish, can wear for a lifetime and not go out of shape. 316l stainless steel jewelry is lead-free, nickel-free, allergy-free, friendly with the human body, and never turns people’s skin green.
