What is the heat treatment specification and metallographic structure of 1Cr13?

1Cr13 heat treatment specification: 1) annealing, slow cooling at 800~900 ℃ or fast cooling at about 750 ℃; 2) Quenching, 950~1000 ℃ oil cooling; 3) Tempering, fast cooling at 700~750 ℃.

Metallographic structure of 1Cr13: the structure is characterized by martensite.

1Cr13 delivery status: generally delivered in heat treatment status, and the type of heat treatment is indicated in the contract; If not specified, the goods shall be delivered without heat treatment.

 

What are the uses of 1Cr13?

1Cr13 can be used to make parts that are resistant to weak corrosion media and bear loads, such as steam turbine blades, hydraulic valve, bolts, nuts, etc., which are mainly used for parts that require high toughness, certain rust resistance and bear impact loads, such as cutting tools, blades, fasteners, hydraulic valve, thermal cracking and sulfur corrosion resistance equipment, etc., and also can be used to make equipment and components that are resistant to weak corrosion media at normal temperature.

 

What is the difference between 1Cr13 stainless steel and 304 stainless steel?

1. Different ingredients

1Cr13 stainless steel contains 0.15% carbon, 13% chromium, C ≤ 0.15, Si ≤ 1.00, Mn ≤ 1.00, P ≤ 0.035, S ≤ 0.030, Cr=11.50~13.50.

The most important elements in 304 are Ni and Cr, but they are not limited to these two elements. According to the common judgment in the industry, as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel.

2. Different physical properties

1Cr13 stainless steel has high strength; Excellent machinability hardens after heat treatment; Magnetic; Not suitable for harsh corrosive environment.

The density of 304 stainless steel is 7.93 g/cm3, also known as 18/8 stainless steel in the industry. It is resistant to high temperature of 800 ℃, with good processing performance and high toughness.

3. Different marking methods

Ferritic and martensitic stainless steels are 400 series, such as 405410443.

Austenitic stainless steels are marked with 200 and 300 series of numbers. For example, some common austenitic stainless steels are marked with 201, 304, 316 and 310. Among the marking methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally refers to the national standard production, 304 generally refers to the ASTM standard production, and SUS 304 refers to the Japanese standard production.

4. Different uses

1Cr13 stainless steel has good corrosion resistance and machinability, general purpose blades, valves, mechanical parts, and class 1 tableware (spoons, forks, knives, etc.).

304 stainless steel is suitable for food processing, storage and transportation. It has good machinability and weldability. Plate heat exchangers, bellows, household products (category 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry, agriculture, ship parts, etc.

 

What are the advantages of 1Cr13 Stainless Steel?

1Cr13 stainless steel is one of the most popular and widely used types of stainless steel. Its high chromium content gives it excellent corrosion resistance, while its high carbon content makes it ideal for applications where strength and hardness are required.

 

What are the disadvantages of 1Cr13 Stainless Steel?

While 1Cr13 stainless steel offers excellent hardness and wear resistance, there are a few potential drawbacks to consider. One downside is that it can be susceptible to corrosion in some environments, especially if not properly cared for. Additionally, 1Cr13 is a bit more expensive than other types of stainless steel, so it may not be the best option for those on a budget.

 

How is 1Cr13 stainless steel heat treated?

1Cr13C stainless steel is a high carbon martensitic stainless steel. It has high strength, good hardness, wear resistance and good corrosion resistance.

1Cr13 can be heat treated at various temperatures to produce a wide range of properties. It can be hardened to Rockwell C 60 by a small amount of tempering. 1Cr13 can also be annealed at a temperature between 800-900 ℃, or rapidly cooled at about 750 ℃. This will give the steel maximum ductility.
