S355NL is a normalized steel (fine-grained steel) in the EN10025-3:2004 standard. Its yield strength and tensile strength correspond to my country's Q345 low alloy steel. NL is required to absorb impact in a low temperature environment of minus 50 degrees. Work test·and the impact value is not less than 27J.

 

S355 is a European standard low alloy high strength plate

 

The steel grade must consist of the following parts:

-Steel name or steel number: The steel name consists of the following parts;

-Steel name or steel number: The steel name consists of the following parts;

-Description of the minimum yield strength in MPa for thicknesses ≤16 mm;

-When feasible, mark the name of the mass component of the impact energy;

- where feasible, mark letters for special purposes;

– If the product is delivered in "+N or +AR" status, it must be marked "+N or +AR".

 

quality level

EN10025-2 quality grades are divided into S355JR, S355J0, S355J2, S355K2,EN10025-23 quality grades are divided into S355N S355NL.

 

chemical composition

Take S355J2 as an example:Deoxidation method: FF; C: ≤ 0.22; Si: ≤ 0.55; Mn: ≤ 1.60; P: ≤ 0.025; S: ≤ 0.025; Cu: ≤ 0.55;

 

 

The main purpose:

S355 has been widely used in the manufacturing of engineering machinery, ships, bridges, high-rise buildings, boilers and pressure vessels, electric power, and various vehicles.

 

 

Specification we supply：

Thickness	3-200mm
Width	1500-4000mm
Length	5000-15000mm

 

 

Process performance: Including metal's weldability, cutting performance, cold and hot processing properties, heat treatment properties, forgeability, uniform structure stability and large cross-section hardenability, etc. When considering the cost of materials, the impact of different eases of material processing and welding on manufacturing costs should also be considered.
