Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
Normal strength shipbuilding structural steel is divided into four grades: A, B, C, and D. The yield strength (not less than 235N/mm^2) of A709 grade 50W carbon steel plate these four grades is the same as the tensile strength (400~520N/mm^2). However, the impact properties of steel plates at different temperatures are different.
SPA-C steel with the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the A709 grade 50W carbon steel plate, SPA-C steel coil thickness should not exceed 25 mm. SPA-C steel’s mechanical properties is yield strength more than 325 MPa, tensile strength more than 450Mpa.
Alloy spring steel is a kind of steel which can improve the mechanical properties, hardenability and other properties of the steel by adding some alloy on the basis of carbon steel to meet the requirements of manufacturing various springs. Its advantages are that it integrates other materials, making spring more stable, durable, long life. A709 grade 50W carbon steel plate, Alloy spring steel has high elastic limit, high yield ratio, high fatigue strength and enough toughness.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other A709 grade 50W carbon steel plate steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market. Let’s work together!
