Ympress Laser was developed from the successful Ympress family. The range contains the most popular grades for laser cutting and consists of one structural steel and two high-strength low-alloy steels. The steel is delivered via dedicated and specialised routes to market and is combined with a dedicated service package. Our technical consultants can answer your questions about the Ympress Laser product range to help you optimise your laser processing operations and to achieve high reliability, maximum production rates and best quality.

State-of-the-art Ympress Laser products offer an important contribution for endusers to further maximise results:

• Faster cutting speed with a clean cut edge, through a well adhered oxide layer and consistent chemical contents
• Simple release of cut parts from sheets through the combination of a clean cut edge and flat low-tension sheet
• Faster setup through a highly consistent product, in all aspects
• Minimal after work of the cut parts through an extremely clean cut edge
• Consistent bending behaviour through fine thickness and mechanical property tolerances
• Suitable for automated processing through consistent properties and quality
• Excellent laser cutting and conventional cutting properties

Ympress Laser additionally offers all the advantages of the Ympress product range.

Ympress Laser can be used for the following applications: 

Ympress® E250C Laser	Ympress® S355MC Laser	Ympress® S420MC Laser
Shelving and racking	Radiator parts	Towing hooks
Profiles for building and construction	Automotive seat parts	Automotive seat parts
	Fuel system parts	Industrial silos
	Yellow goods

In these applications the high strength of steel is used to save weight and/or to increase load bearing capacity.

Ympress Laser steel complies with the following standards:

Impact tests can be performed on request.         
Note: For Ympress E250C Laser > 12.7 mm the impact test is limited according to EN 10025-2, 2004, grade S235J0

The following values apply to typical and guaranteed mechanical properties of Ympress Laser:

• For Ympress E250C Laser the values of the tensile test apply to test bars transverse to the rolling direction
• For Ympress S355MC Laser and S420MC Laser the values of the tensile test apply to test bars parallel to the rolling direction
• The values of the bend test apply to test bars transverse to the rolling direction
