Determination of yield point and yield strength of 1.8909 EN 10025-6 high strength steel

The company has 1.8909 EN 10025-6 high strength steel advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience 1.8909 EN 10025-6 high strength steel, we have accumulated a large number of customers at home and abroad, and won unanimous praise.

In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, 1.8909 EN 10025-6 high strength steel is of high quality? First of all, check whether there are cracks on the surface of the 1.8909 EN 10025-6 high strength steel plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.

1.8909 EN 10025-6 high strength steel, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. 1.8909 EN 10025-6 high strength steel, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. 1.8909 EN 10025-6 high strength steel, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.

Laser cutting, it is a specific way of cutting 1.8909 EN 10025-6 high strength steel steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting 1.8909 EN 10025-6 high strength steel speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.

Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. 1.8909 EN 10025-6 high strength steel, 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
