About Stainless steel
About 304 vs 316 Stainless steel, is an alloy metal composed of various elements, among which stainless steel contains a small amount of carbon and chromium. This excellent performance comes from chromium, which forms a protective film on the surface of the material to protect the materials from corrosion. when it oxidizes when exposed to oxygen, the material can repair itself. Stainless steel is also an environmentally material because stainless steel can be reused.
Stainless steel has the characteristics of anti-rust. The surface is smooth and has a perfect metallic luster. Stainless steel can be manufactured into bar stock, sheet， and tube. Many industries are involved. For example, stainless steel can be made into plates, which are widely used in the furniture and home appliance industries. The manufactured rods, wires， and tubes are used in the construction industry.
Stainless steel has excellent cleaning properties, even comparable to glass. Stainless steel’s strength, ease of sterilization, and corrosion resistance make it commonly used in medical devices and equipment. For example, surgical equipment, surgical equipment accessories, and more.
Application of 304 vs 316 in CNC machining
Stainless steel has good processability and is suitable for various processing methods,include:
5-axis Machining
Stainless steel is suitable for 5-axis machining, the program is set by the engineer, and the complex parts can be unlocked by machining stainless steel parts on multiple surfaces.
CNC Milling
The production of milled stainless steel is very simple. The engineer sets the program on the computer. When the tool runs with the program, the milled stainless steel parts can be obtained without repeated manual operations.
Laser Cutting
Laser Cutting aluminum plate processing is also a very common processing mode, through laser cutting and accurate aluminum sheets through the drawings provided by the designer
Rapid Prototyping
Rapid prototyping is processed through computer programming with 3D printing or other programs so that you can quickly obtain your customized parts.
Advantages and characteristics of 304 vs 316
Grades 304 vs 316 are stainless steel with most of the same characteristics. The most critical differences are the chemicals added, and ratios.
Grade 304 Characteristics and Applications
304 is the most common stainless steel Material in daily life. Among them, the steel content of 304 is 18 percent, the chromium content is 20 percent, and the nickel content is 8 percent. 304 contains a small amount of carbon and manganese. These elements make it antioxidant and easy to clean and sanitize
304 is a type of austenitic stainless steel. The thermal conductivity and electrical conductivity of 304 are even lower than that of carbon steel. It is widely used because of its easy processing and good cleaning performance.
The tensile strength of 304 is within 800, and the 316melting point is as high as 1450 degrees. In order not to damage its anti-corrosion performance, it is not recommended to use it continuously in water with a water temperature as high as 425-860°C.
304 stainless steel is commonly used in:
kitchen Utensils
Tableware
Grill
Appliance Housings
Food Container
Flange, Pipeline
Nuts, Bolts, Impellers
Pharmaceutical Production Equipment and Medical Equipment
Grade 316 Characteristics and Application
316 is also a kind of alloy, which is one of the most common austenitic stainless steels, second only to 304.316 is composed of 18% chromium, 12% nickel, and 3% molybdenum, which also contains a small amount of silicon, phosphorus, and Sulfur, which is the main difference between 316 and 304 stainless steel.
The melting point of 316 is as high as 1400°C, the mechanical tensile strength is within 620 MPa, and the maximum hardness is HB 149.
The addition of molybdenum to 316 not only improves the chloride corrosion resistance of 316 stainless steel but also makes 316 more resistant to high temperatures. Due to this excellent performance, 316 materials are often used in the manufacture of pumps and chemical equipment.
Application of Grade 316
The addition of molybdenum in stainless steel 316 makes 316 more corrosion-resistant than other alloys. With its excellent rust and corrosion resistance, 316 is one of the metals used in marine environments. 316 stainless steel is easy to clean, easy to disinfect, and durable, and is often used in hospitals.
Common applications of 316:
water heater
boat railing
boat ladder
Surgical Equipment
Medical instrument/equipment
chemical processing equipment
304 and 316 are both stainless steel but the price is still different. For example, the nickel content in 316 is higher than that of 304, and molybdenum is added to 316, so the price of 316 is higher than 304.
