FAQs
Frequently Asked Questions
Here are some common questions and answers. If you still have questions, don’t hesitate to contact us.
1. What is EN 10210?
EN 10210 is the standard for hot finished hollow sections, and covers a number of subtly different products, manufactured in different ways and with different properties. Tata Steel’s Celsius range, for example, is designated within the standard as S355NH because it is full-body normalised.
2. What is the difference between EN10210 and EN10219?
In EN 10210, the grade refers to the steel in the finished hollow section; In EN 10219, the grade refers to the steel feedstock used for cold-forming of the hollow section, so the metallurgy will be modified in the cold forming process.
3. What is En 10210 steel grade?
EN 10210 Grade S355J2H Pipe and Tube are low-cost Low Carbon Steel Pipes and Tubes with maximum 0.22% of carbon content with combination of maximum 1.6% of manganese easy to form and shape. The pipes are manufactured as per EN Specification and commercially known as carbon steel pipes or mild steel pipes.
4. Is EN10210 hot finished?
EN 10210 is the standard for hot finished hollow sections, and covers a number of subtly different products, manufactured in different ways and with different properties.
5. What is the yield strength of EN 10210?
The material has silicon, manganese, phosphorus and sulfur in the composition. The combination of elements in the EN 10210 S355J2H Material provides it with 355MPa minimum yield strength and 630MPa minimum tensile strength.
6. What is standard EN 10210-2
This document specifies tolerances for hot finished circular, square, rectangular and elliptical structural hollow sections, manufactured in wall thicknesses up to 120 mm, in the following size ranges: – Circular: Outside diameters up to 2 500 mm; – Square: Outside dimensions up to 800 mm × 800 mm; – Rectangular: …
