Steel, said steel grades referred Editing Overview steel, is the name for each specific steel products taken, is that people understand a common language steel. Representation of steel, according to national standards, "Steel Grades representation" (GB221-79) specified in Laiwu 42crmo, using phonetic alphabet, chemical element symbols and numerals represent a combination of methods. Namely: ① steel chemical elements in the use of international chemical symbols, such as Si 42crmo ingredients, Mn, Cr ...... etc. Mixed rare earth elements with "RE" (or "Xt"). ② product name, purpose, smelting and casting methods, commonly used abbreviations pinyin letters. ③ steel main chemical element content (%) using Arabic numerals. Pickling requires editing workshop floor and equipment commonly used basic anti-corrosion resin mortar floor structure, with a total thickness of about 7-10 mm), the structure is: 1-2 Road + fiberglass primer (2 fabric 3 oil) isolation layer + resin mortar layer (5-7 mm) + surface layer (about 1 mm). Floor, anti-corrosion equipment foundation are currently using epoxy resin vinyl resin, but the choice of primer construction unit also used to make epoxy primer material to increase the adhesion properties of the resin and the grassroots level. Generally be applied epoxy amine curing agent, curing oily substance floating to the surface, and then not be able to match a good vinyl resin bonding and the need for surface after curing 42CrMo alloy steel bar processing can be carried out subsequent anti-corrosion structure construction, if not properly handled easily layered and cracking. According to experts, vinyl resins and epoxy adhesive force between the concrete foundation reaches more than 2MPa Suzhou 42crmo, so the epoxy vinyl resin as a primer material already has sufficient bonding properties, and therefore recommend direct 42CrMo alloy steel bar with epoxy vinyl resin as a primer material base, the other layers using the same epoxy vinyl resin. 42crmo tube, Sanming 42crmo, Katherine source of steel provided by source Pipe Co., Ltd.
