1. Overview of DIN Standards
DIN standards cover a wide range of materials and products, from fasteners to machinery components and even entire systems. Each standard is typically identified by a unique number (for example, DIN 933 for hexagon bolts), with specific guidelines on dimensions, mechanical properties, materials, and testing methods.
These standards ensure that products conform to safety norms, and perform reliably in diverse environments and applications.
2. Dimensions and Tolerances of DIN Standards
The dimensions and tolerances of DIN standards vary depending on the type of material or product being specified. Below is a table listing some common DIN standards with dimensions and tolerances for various products.
DIN Standard | Description | Dimension (mm) | Tolerance |
---|---|---|---|
DIN 933 | Hexagon Bolts | M6 to M30 | ISO 68-1 |
DIN 976 | Threaded Rods | M8 to M100 | ISO 965-1 |
DIN 17100 | Carbon Steel Plates | 4 mm to 100 mm thick | ± 1% |
DIN 2391 | Steel Tubes for Mechanical Engineering | OD: 6 mm to 101.6 mm | ± 0.4 mm |
DIN 6330 | Ball Bearing Housings | Inner diameter 10 mm to 100 mm | ± 0.2 mm |
3. Mechanical Properties Based on DIN Standards
Mechanical properties such as tensile strength, yield strength, hardness, and elongation are critical factors that are specified in DIN standards for materials. Here’s a table that summarizes some of the mechanical properties of materials according to DIN.
DIN Standard | Material | Tensile Strength | Yield Strength | Hardness |
---|---|---|---|---|
DIN 17100 | Structural Steel | 400-600 MPa | 235-350 MPa | 140 HB |
DIN 2391 | Cold Drawn Precision Steel Tubes | 450-650 MPa | 250-350 MPa | 160 HB |
DIN 488 | Reinforced Concrete Bars | 500-600 MPa | 250-350 MPa | – |
DIN 540 | Alloy Steel | 500-700 MPa | 300-400 MPa | 180 HB |
4. Grades of Materials According to DIN Standards
Materials are classified into different grades based on their mechanical properties, intended use, and performance. The following table outlines the grades for some common materials according to DIN standards:
DIN Standard | Material | Grade | Chemical Composition |
---|---|---|---|
DIN 17100 | Carbon Steel | St 37-2, St 52-3 | C ≤ 0.25%, Mn ≤ 1.60% |
DIN 2391 | Steel Tubes | St 52.4, E235, E355 | C ≤ 0.20%, Mn ≤ 1.50% |
DIN 1.7225 | Alloy Steel | 42CrMo4 | C: 0.38%, Cr: 1.00%, Mo: 0.25% |
DIN 17172 | Stainless Steel | 1.4301 (304), 1.4404 (316) | Cr: 18%, Ni: 8% |
5. Price Variations Based on DIN Standards
Prices for materials or products adhering to DIN standards can fluctuate based on factors like material type, grade, quantity, and market conditions. Below is an estimation of price ranges for some common products:
Product | Price Range (USD) | DIN Standard |
---|---|---|
Hexagon Bolts (M10) | $0.10 – $0.50 | DIN 933 |
Steel Sheets (5 mm thick) | $400 – $700 per ton | DIN 17100 |
Steel Tubes (OD 50 mm) | $3 – $8 per meter | DIN 2391 |
Ball Bearing Housings | $5 – $20 | DIN 6330 |
Note: Prices may vary depending on suppliers, quantities, and the type of steel or material selected.
6. Applications of DIN Standards in Various Industries
DIN standards are used extensively across several industries due to their universal applicability. Below is a table summarizing the most common applications of DIN standards across different sectors:
Industry | Application | Relevant DIN Standards |
---|---|---|
Manufacturing | Production of bolts, nuts, and screws | DIN 933, DIN 976, DIN 931 |
Automotive | Production of fasteners, exhaust pipes, and chassis parts | DIN 17240, DIN 2391 |
