Q355NH steel bar for boiler drums

On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy Q355NH steel bar steel screw (Carbon and Alloy Steel Threaded Rod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of Q355NH steel bar carbon alloy steel screws from China and India, according to the itc's affirmative ruling.

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for Q355NH steel bar various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several Q355NH steel bar after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the Q355NH steel bar steel pipes. And do PT, MT and so on tests for the pipe fittings. We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.

Processing performance of quenched and tempered steel: Q355NH steel bar plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.

35# steel is a high-quality medium carbon carbon structural steel, with good plasticity and appropriate strength, good process performance, and acceptable welding performance. It Q355NH steel bar is often delivered in normalized and tempered state. 35 # steel is widely used in the manufacture of various forged and hot-pressed parts, cold-drawn and Q355NH steel bar upset forged steel, seamless steel tubes, and parts in machinery manufacturing.
