How to distinguish the normal floating rust and rusting of a633 alloy steel and a36 carbon steel

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, a633 alloy steel and a36 carbon steel quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the a633 alloy steel and a36 carbon steel International leading steel materials supplier.

Pipeline steel plays an important role in pipeline transportation. How many types of a633 alloy steel and a36 carbon steel, pipeline steel are there? At present, pipeline steel can be divided into the following four categories according to microstructure. First, pearlitic pipeline steel. The basic components of pearlitic pipeline steel are carbon and manganese, generally speaking, the content is 0.10% - 0.20%, and the manganese content is 1.30% - 1.70%. It is generally produced by hot rolling or normalizing heat treatment process. Second, acicular ferrite pipeline steel. Third, martensitic pipeline steel. Fourth, tempered sorbite pipeline steel.

Our stainless steel mainly is stainless steel plate/Coil. We keep 2600 tons stainless steel plate and coil a633 alloy steel and a36 carbon steel in stock. And we refresh the our new stock every month. All the stock products from reputable mills like like TISCO, ZPSS, IISCO, LISCO, Bao steel and so on. We put all our products in Shanghai and Tianjin warehouse, which is near the loading port.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. a633 alloy steel and a36 carbon steel, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. a633 alloy steel and a36 carbon steel, Q420C steel has good mechanical properties and weldability, good cold and hot workability.

There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with a633 alloy steel and a36 carbon steel high-quality steel plates, the excellent quality from specialty. With good reputation, high-quality products, strong strength, and low prices, we welcome the clients from the world to come to visit our factory.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
