The introduction of mild steel plate

The mild steel plate is the abbreviation of ordinary carbon structural steel. The carbon content is less than 0.38%, with less than 0.25% being the most common. The mild steel plate is the abbreviation of ordinary carbon structural steel. The carbon content is less than 0.38%, with less than 0.25% most commonly used. It is a low carbon steel, and each metal grade indicates the lowest yield point of the steel when the thickness is less than 16mm. Compared to high quality carbon steels, there are wider restrictions on carbon content, range of properties and the content of phosphorus, sulfur and other residual elements. China and some countries according to the delivery guarantee conditions, the mild steel plate into three categories: Class A steel (Class A steel), only to ensure the mechanical properties, not to ensure the chemical composition, Class B steel (Class B steel), only to ensure the chemical composition, not to ensure the mechanical properties; special steel (Class C steel), both to ensure the chemical composition, but also to ensure the mechanical properties. Do you know about the grade of mild steel plate? The following paper will take you to know about the mild steel plate and the mild steel plate manufacturer. The following paper will take you to know about the mild steel plate and the mild steel plate manufacturer.

The grade of mild steel plate

The following paper will take you to know about the grade of mild steel plate. The mild steel plate is divided into five grades according to its yield strength grade, the mild steel plate structure commonly used grade Q235 steel. The grade of steel is composed of four parts in sequence: the letter representing the yield point, the value of the yield point, the quality grade symbol, and the deoxidation method symbol. For example, Q235AF, where "Q", is the first letter of the steel yield point "Qu" Hanyu Pinyin; "235" is the yield point value of the grade, indicating that the yield strength of the steel is "235N/MM "A'' is the quality grade of steel, which is divided into four grades: A, B, C and D. Grade "A" is the lowest grade, and grade "D" is the highest grade; "F" is the first letter of the Chinese character for "boiling" of boiling steel. First letter, indicating that the steel is boiling steel. If the end of the steel grade is marked with the letter "B", it indicates that the steel is semi-sedated steel, "B" is the first letter of the word "semi" in Hanyu Pinyin for semi-sedated steel; "Z Z" is the first letter of the word "town" in Hanyu Pinyin for sedated steel; "TZ" is the first letter of the word "special town" for special sedated steel. Hanyu Pinyin the first letter, on behalf of special sedimentation steel. In the mild steel plate grade composition, "Z" and "TZ" symbols are omitted, "F", "B", "Z " and "TZ" four kinds of symbols indicate the degree of deoxidation when casting ingots. Sedimentation steel is the steel with aluminum, silicon, etc. fully deoxidized, less gas released during casting, good quality, but expensive. Boiling steel is deoxygenated with ferromanganese, due to insufficient deoxygenation, boiling phenomenon in the ingot when casting, the quality is not uniform, but the productivity is higher. Between the sedimentation steel and boiling steel is semi-sedimentation steel.
