A carbon steel plate has usually been considered as the steel that does not contain much alloy steel elements, also named as mild steel. Generally, elements are C, Mn, P, S, Si, besides these, there are no minimum limits for elements of Al, Cr, Ni, Mo, V, etc.
Carbon steel plates are available in different grades depending on the carbon content and strength.
As the content of Carbon increase, the steel plate hardness increases.
Low carbon steel plate: For carbon content 0.06% to 0.25%, also we call it mild steel plate.
Medium carbon steel plate: C content from 0.25% to 0.55%.
High carbon steel plate: 0.55% to 1.0%, also called hard steel plate.
Low carbon steel is the most common form, and it's very malleable and ductile. Medium carbon steel balances ductility as well as strength for excellent wear resistance. High carbon steel is exceptionally strong, while ultra-high carbon steel can be tempered to even greater hardness but no malleability.
As the percentage of carbon gets larger, steel can become harder and stronger through heat-treating. Carbon steel is usually heated to change the mechanical properties of steel, usually ductility, hardness, strength, and resistance of impact. Increasing the carbon content of carbon steel makes it harder and stronger, but reduces the steel`s ability to be welded, making it more brittle.
Carbon steel plate is most often used for structural purposes such as buildings, yet it has the flexibility to be worked into ornate designs. Low carbon steel sheet (wrought iron) is typically used for fences, chain links, gates, and railings. Structural steel (medium carbon steel) is used in cars, refrigerators, washing machines, buildings, and bridges. The steel sheets are normally made up of medium carbon steel.

This company carefully analyzes the technical problems in the exploration and development of gas fields, and overcomes the bottleneck that restricts the drilling speed as a breakthrough. According to the characteristics of different well types, various research tests are carried out to speed up the drilling speed. According to different well types, the drilling fluid performance is optimized, which not only solves the anti-collapse and plugging ability of the well, but also liberates the mechanical drilling speed to the maximum extent, improves the drilling speed, and continuously refreshes the production index, creating 8 items. Gas field drilling production indicators.
At the same time, the company organized technical personnel to complete the research on “Changqing gas field optimization technology for natural gas drilling†and “Extension application of solid-free drilling fluid system in natural wellsâ€. These scientific research results are solved after being applied in production. The technical problems in production provide a strong technical guarantee for safe and fast operation of drilling production.
As of December 15, this year, the company completed a total of 601,909,000 meters of gas wells, 207 gas wells and 208 gas wells per year.
Changqing drilling research and development to promote gas field drilling speed
Recently, it was learned from the Changqing Gas Field Drilling Technology Symposium held by the Changqing Petroleum Exploration Bureau Drilling Corporation that this year, in the face of the heavy capacity building task of the gas field, the company carried out the test and promotion of new technologies such as PDC bit and screw drilling tools. Application, to achieve a substantial increase in drilling production.
