Corrosion resistance of Super13cr stainless steel round steel for drilling tools

Super13Cr is a martensitic stainless steel with good corrosion resistance and excellent strength, mainly used in offshore oil projects, OTG pipelines, casings, and underground projects. It is a super stainless steel that improves its strength and hardness, as well as toughness, by reducing the carbon content (carbon content is 0.03%) and increasing the nickel content (4.5-5.5%) and molybdenum content (1.5-2.5%). This material overcomes the shortcomings of traditional martensite such as poor stress crack sensitivity and poor weldability during welding, and therefore has higher corrosion resistance and better welding performance. Super13Cr has a wide range of applications, including but not limited to automotive, metal products, precision electronics, mechanical manufacturing, pressure vessels, chemical equipment, etc.

Stainless steel round steel belongs to the category of long materials and also to the category of rods. The so-called stainless steel round steel refers to long materials with a uniform circular cross-section, generally about four meters long. It can be divided into light circles and black bars. The so-called light circle refers to a smooth surface that has undergone quasi rolling treatment; The so-called black rod refers to a surface that is black and coarse, directly hot-rolled.

Stainless steel round steel has the following characteristics:

1. Corrosion resistance: Stainless steel round steel can resist rusting and corrosion in media such as atmosphere, water, acid, and alkali, and has good corrosion resistance. It can maintain surface brightness and color change.

2. High temperature resistance: Stainless steel round steel can still maintain good stability in high temperature environments, without deformation, softening, or cracking, and can be used in high-temperature situations.

3. High strength: Stainless steel round steel has a compact and strong structure, excellent mechanical properties, and can be used under harsh conditions such as high strength and high pressure.

4. Convenient processing: Stainless steel round steel can be processed in various ways, such as welding, cutting, drilling, punching, etc. It can be customized according to actual needs.
