Analysis of fault layer problem of CCS A40 bulk ore carrier steel

The difference between q345 and q235 steel CCS A40 bulk ore carrier steel
The lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.

Due to vast experience & concerted efforts of all employees, we are known as a reliable supplier of API 5l Line Pipe, seamless pipes and ERW pipes. Our CCS A40 bulk ore carrier steel customers in the world has about 4000 clients in 70 countries such as Bangladesh, Saudi Arabia, Iran, Iraq, United Arab Emirates, Qatar, Bahrain, Oman, Kuwait, Turkey, Egypt, Jordan, Philippine, Singapore, Malaysia, Indonesia, Thailand, Vietnam, South Korea, Japan, Sri Lanka, Bangladesh, Argentina, Brazil, Colombia, Guyana, United States Of America, Canada, Mexico, Jamaica, Germany, France, Italy, United Kingdom, Spain, Netherlands, Belgium.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of CCS A40 bulk ore carrier steel welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used CCS A40 bulk ore carrier steel, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

Our company will accept the product quality objection registration record, pass it to the CCS A40 bulk ore carrier steel production unit and relevant departments, and timely coordinate the supervision of product CCS A40 bulk ore carrier steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
