DIN 1.2316 grade of steel, as a material, is actually a variety of chrome-molybdenum tool steel. This particular variety has earned popularity due to its very high resistance to corrosion. Moreover, this variant of steel offers unmatched toughness, better polishability, toughness, excellent heat resistance, as well as wear-resistant capacity. Though it has many utilities, engineers often use this to process plastic materials like PVC, which are chemically aggressive.
Why choose 1.2316 Steel?
This versatile metal is useful in various applications. Apart from the PVC manufacturers, you can find mechanics choosing it to make worn parts, fixtures, dies, cutting tools, and many other worn parts. It has also become a popular alternative to another versatile tool variety, 1.2083. This is because the former base has better corrosion resistance capacity than the latter. This makes it ideal for plastic products that have abrasive fillers.
General Steel Properties
Another unique property of 1.2316 is its uniform hardness. This enhances its machinability. Moreover, this tool has better polishability and a smoother surface finish.
Chemical Composition
In brief, the chemical content of this type of steel include:
· Carbon (or C): 0.18%
· Chromium (or Cr): 12.5%
· Molybdenum (or Mo): 1.5%
· Manganese (or Mn): 0.5%
· Silicon (or Si): 0.4%
· Phosphorus (or P): 0.04%
· Sulfur (or S): 0.03%
Mechanical Properties
Some of the most important mechanical properties of this type of steel are that it has:
Tensile strength of about 900-1050 MegaPascals or MPa/ about 130,500-152,200 pounds per square inch (psi)
Yield strength: 700-800 MPa or about 101,500-116,000 psi
10% elongation at break
62-67 High Rupturing Capacity or HRC
Forging of 1.2316
This type of steel forges slowly but steadily at about 1000 degrees Celsius. It is also necessary to cool down the metal in thermoinsulating metals or in the furnace itself.
Heat Treatment
The most dedicated 1.2316 Steel Material suppliers deliver their products in a pre-hardened condition. Hence, this type of steel does not usually need any heat treatment.
Annealing
The optimal annealing temperature for 1.2316 Steel is about 760 - 800 °C for 4-5 hours. Also, it is important to offer controlled and slow cooling in a wide range of temperatures. It can vary anything from 10-20 degrees Celsius to 650 degrees Celsius. Mechanics also cool it in the air.
Tempering
The hardness of this type of steel would vary on the basis of tempering heat. It usually ranges from 32 High Rupturing Capacity (HRC) to 49 HRC.
The Best Applications
Apart from the PVC manufacturing industry, the 1.2316 Steel Material is helpful in procedures involving:
Extrusion tools.
Die casting moulds.
Injection moulds, especially for plastic varieties like polycarbonate and ABS.
Applications like forging, metal stamping, as well as cutting.
Different types of fixtures, especially those that position and hold work pieces while machining.
Manufacture of cutting tools like drill bits, milling cutters, and even end mills.
The process involves the manufacture of various wear parts like bearings, bushings, and gear.
Disadvantages
Despite all the advantages, the 1.2316 steel variety has some downsides as well. These include:
· Relatively high cost.
· Comparatively less tensile strength than other varieties.
· In some cases, it can be tough to machine.
Before opting for this variety over other steel types, make sure to consult with your local steel suppliers for some practical help.
