PN-EN 10219-1 Cold Finished ERW Mild Steel Tubes Hollow Sections

Production Information : PN-EN 10219-1,2 Structural steel tubes of non-alloy and fine grain steels

·

PN-EN10219-1,2

Cold finished structural welded hollow sections of non-alloy and fine grain steels

The scope of the standard includes: cold-formed round, square, and rectangular welded hollow sections without subsequent thermal processing.

The steels are classified as follows similarly to the classification provided in the EN 10210 standard:

· Non-alloy steels

· Fine grain steels

Non-alloy steels are classified in the same way as specified in the EN 10210 standard

In the case of resistance classes of fine grain steels, four quality groups have been established:

· N resilience testing at the temperature of –20 °C

· NL resilience testing at the temperature of –50 ° C

· M resilience testing at the temperature of –20 ° C

· ML resilience testing at the temperature of –50 °C

The steels are designated with the letter “S”, then with the minimum value of the yield strength limit “Re” (e.g. 235, 275, 355, 420, 460), followed by the letters that designate the manufacturing class ( JR , J0 ,J2 ,N ,NL ,M , ML) and the letter “H” which designates a hollow product.

The letters N designate the production input in the Normalized condition

The letters M designate the production input in the After Thermomechanical Processing condition

ATTENTION! The tests performed on those sections are the same as specified in the EN 10210 standard
