C45 steel heat treatment: Quenching has low hardenability, and it is easy to cause uneven hardness of the drill rod during heat treatment, resulting in deformation or even cracking. The hardness after quenching is about 42 degrees, which is much lower than the 55 degrees of 42CrMo brazing rod. Therefore, the wear resistance is extremely poor. Due to its low price, the BV AH36 chemical vessels steel materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.
The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values. Advanced equipment, scientific standardized management, strict quality assurance system and high-quality team are the core competitiveness of the company. The company will continue to provide customers with BV AH36 chemical vessels steel high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".
Nickel element is mainly used to form and stabilize the austenite structure, so that the BV AH36 chemical vessels steel steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
Oxygen is a harmful element in BV AH36 chemical vessels steel steel. With the increase of oxygen content, the strength of BV AH36 chemical vessels steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of BV AH36 chemical vessels steel steel.
