DIN 1.2316, also known as X36CrMo17, is a martensitic stainless steel alloy with good corrosion resistance, toughness, heat resistance, and wear resistance, commonly used for plastic molds, especially those processing chemically aggressive materials like PVC. Here's a more detailed description:
• Material Type: Martensitic stainless chromium steel. 
• Composition: Characterized by a high chromium content (around 17%), with molybdenum also contributing to its properties. 
• Properties:
  • Corrosion Resistance: Superior corrosion resistance compared to steel grade 1.2083, making it suitable for processing chemically aggressive materials. 
  • Toughness: Possesses good toughness, allowing it to withstand the stresses of plastic molding. 
  • Heat Resistance: Resistant to heat, important for maintaining dimensional stability during molding cycles. 
  • Wear Resistance: Good wear resistance, contributing to the longevity of the molds. 
  • Polishability: Easy to polish, resulting in a high surface finish. 
  • Uniform Hardness: Maintains uniform hardness across all dimensions. 
• Applications:
  • Plastic Molds: Widely used for plastic injection molds, especially for processing chemically aggressive plastics like PVC. 
  • Other Tools: Also used for tools for processing plastic materials, extrusion tools, and compressor parts. 
• Pre-Hardened Condition: Typically supplied in a pre-hardened condition (33-38 HRC). 
• Alternatives: Often used in place of steel grade 1.2083 due to its superior corrosion resistance. 
• Equivalents:
  • DIN: X36CrMo17 
  • AISI: 422 

Die steel round bars are high-strength steel bars, typically made from high-carbon, high-alloy steels, used for producing dies for metalworking operations like stamping, extrusion, forging, and cold heading, known for their hardness, toughness, and wear resistance. Here's a more detailed description:Material and Properties:
• High-Strength Steel:Die steel round bars are crafted from high-strength steels, often with special alloying additions to ordinary high-carbon steels. 
• Heat Treatment:These bars are heat-treated to achieve the desired hardness, toughness, and wear resistance. 
• Common Grades:Some common die steel grades include D2, D3, H-11, H-13, and EN31. 
• Characteristics:They offer excellent hardness, toughness, and wear resistance, making them suitable for demanding die applications. 
• Applications:They are used to make dies for a variety of metalworking operations, including stamping, extrusion, forging, and cold heading. 
Types and Availability:
• Round Bars:They are available in various diameters and lengths to suit different applications. 
• Other Forms:Die steel can also be found in flat, square, plate, and sheet forms. 

D2 Grade Introduction:D2 Steel is an air-hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion-resistant properties. It is heat treatable and will offer a hardness in the range of 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening. D2 steel’s high chromium content gives it mild corrosion-resisting properties in the hardened conditions. A high carbon high chromium tool steel grade offering very high wear resistance and toughness. D2 tool steel hardens in air with a low order of movement and offers a measure of corrosion resistance when polished. Commonly used for tools operating under conditions of severe wear and abrasion or as an alternative to oil hardening tool steel grades when long runs are required. D2 Grade Application:Typical applications for D2 Steel: 

Stamping or Forming Dies

Punches

Forming Rolls

Knives, slitters, shear blades

Tools

Scrap choppers

Tyre shredders
