The company has allocated special environmental protection facilities for all NV D32 ore carrier steel pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, NV D32 ore carrier steel steel mill scale, environmental protection dust has reached 100%.
Steel transportation because of the special material of NV D32 ore carrier steel steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the NV D32 ore carrier steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between NV D32 ore carrier steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related NV D32 ore carrier steel products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.
10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. NV D32 ore carrier steel, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.
Continue to refine and improve the company's common core values.Corporate values are the evaluation criteria for the production and operation behavior, products, services provided, social reputation and credit of enterprises, the biggest NV D32 ore carrier steel goal pursued by enterprises and the criteria for judging things accordingly, and the core of corporate culture. Companies in the extraction of common value note: simplicity; Unity of coordination; NV D32 ore carrier steel Systemic; Respect for talents; Focus on giving back to society; Try to make a factual argument in order to gain wider acceptance.
