1.4307 Physical Properties.
Stainless steel is a kind of steel with excellent corrosion resistance, where 14307 is a stainless steel variety with a wide range of applications.
First, a comprehensive introduction.
1.4307 is a low-carbon stainless steel with 18% chromium and 8% nickel, also known as 304L stainless steel. It is a variant of 304 stainless steel with the same chemical composition but with a low carbon content that improves its corrosion resistance. 1.4307 has good corrosion resistance, strength and processing properties, and is widely used in chemical, petroleum, pharmaceutical, food industry and other fields.
2. Characteristics. 1.The 4307 has the following characteristics:
1.Good corrosion resistance:14307 has good corrosion resistance and can withstand some corrosive media, such as acid, alkali, salt, etc.
2.Good processing properties:14307 has good machinability and can be used for cold working, hot working, welding and forging processes.
3.High strength: 14307 has high strength and can meet a variety of usage requirements.
4.Good low-temperature performance:14307 retains its mechanical properties and corrosion resistance at low temperatures.
5.Magnetism: 14307 is a non-magnetic material and does not magnetize other materials.
3. Preparation process.
1.The preparation process of 4307 mainly has the following aspects:
1.Smelting process: 1The smelting process of 4307 is to smelt and mix metal raw materials such as iron, nickel, chromium, etc., and then cool them into billets for processing.
2.Calendering preparation: by combining 14307 blanks are calendered to make plates, round bars and other products.
3.Forging preparation: by placing 14307 blanks are forged and processed into forgings, forging rings and other products.
4.Heat treatment process: through 14307 is heat treated, which can change its grain and mechanical properties.
5.Cold working process: through 14307 is cold-rolled, cold-drawn and other processes, which can change its shape and mechanical properties.
IV. Conclusions. 1.4307 has good corrosion resistance, strength and processing properties, and is widely used in chemical, petroleum, pharmaceutical, food industry and other fields. Its preparation process includes smelting, calendering, forging, heat treatment and cold working. During use, it is necessary to pay attention to prevent problems such as intergranular corrosion and fatigue cracks to ensure its performance and service life.
