Bending of Strenx
Strenx Bending Process:
Bending is a process by which metal can be deformed by plastically deforming the material and changing its shape. The material is subjected to a stress greater than the yield strength but less than the ultimate tensile strength. The surface of the material does not change much. Bending generally refers to the deformation around an axis.
BENDING FORCE
Typical tensile strength values to calculate bend force.
| TYPE OF STEEL | TYPICAL TENSILE STRENGTH (MPa) |
|---|---|
| Strenx 600 MC | 760 |
| Strenx 650 MC | 800 |
| Strenx 700, 700 MC, 700 PLUS | 860, 850, 840 |
| Strenx 900, 900 MC, 900 PLUS | 1010, 1150, 1060 |
| Strenx 960, 960 MC, 960 PLUS | 1060, 1200, 1120 |
| Strenx 1100, 1100 MC | 1440, 1320 |
| Strenx 1300 | 1530 |
P = b • t 2 • Rm / (W-Rd-Rp) • 9 800
P = Bend force, tons (metric) t = Plate thickness, mm
W = Die width, mm (figure 1) b = Bend length, mm
Rm = Tensile strength, MPa (table 1) Rd = Die entry radius, mm
Rp = Punch radius, mm
The SSAB Bending Formula© is verified by tests for 90° bends
The bending recommendations for Strenx strip products are based on fixed die edges and normal friction (no lubrication).
Ri/t applies for all bend directions. Ri/t stands for inner radius on the sheet (Ri) divided by sheet thickness (t).

Cutting of Strenx
Strenx Cutting Process:
Strenx is clean steel, and it is performance steel. This steel, along with its low alloy content, makes them very easy to cut. Strenx steel is suitable for all thermal cutting methods.
These cutting methods are:
• Oxy-fuel cutting,
• Plasma cutting
• Laser cutting.
Strenx steel grade is also ideal for cold cutting processes. Laser cutting is faster than oxyfuel cutting and gives higher cut edge quality than plasma cutting. Laser or plasma cutting is preferable to oxy-fuel cutting due to oxy-fuel cutting supplies more heat and thus raises the temperature of the workpiece.
WELDING OF STRENX
Strenx Welding Process:
Welding is a fabrication process whereby two or more parts are fused by means of heat, pressure or both, forming a join as the parts cool. Welding is typically used on metals and thermoplastics, but can also be used on wood. The completed welded joint can be referred to as a weldment.
Some welding methods are as follows:
• MAG Welding
• MMA Welding
• Tungsten Inert Gas welding
• Plasma welding
• Submerged arc welding
• Laser welding
Metal Active Gas welding is the most commonly used welding method in the industry today. One of the reasons for this is because metal active gas welding is very easy to automate.
