Common corrosion types and causes of S690QL material specification

The shipping department of the company arranges shipping booking for customers' goods in advance, and makes good matching with inland transportation. Effectively manage and follow up the customer's shipping schedule and give feedback to customers in time. At the same time, the shipping department has a keen insight into the shipping market in different periods to reduce the transportation cost for the company and customers.

Advantages of JIS G3101 SS400: Compared with other S690QL material specification steel standards, the steel made of SS400 carbon steel is popular because of its proper tensile strength and toughness, good plasticity, welding performance and processing performance. The thickness of the S690QL material specification steel plate ranges from steel plate to super thick steel plate.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest S690QL material specification processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain S690QL material specification by rolling method.

Q550C steel belongs to low alloy high strength steel. Chemical composition of Q550C steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 0.80, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. Mechanical properties of Q550C steel: yield strength ≥ 550 MPa, tensile strength 600-780 MPa, elongation after fracture ≥ 16%, impact energy ≥ 55J. S690QL material specification, Q550C steel is mainly used for manufacturing various large-scale engineering structural components and construction machinery. Due to its high strength, Q550C steel can meet the requirements of large-scale and lightweight construction machinery.

Management information and high efficiency. Because of the rapid flow of S690QL material specification goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S690QL material specification EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
