DIN2391 cold drawn seamless steel tube with germany standard

synopsis of process routing

quality carbon steel-cold drawn-heat treatment without oxidization (NBK status)- nondestructive testing, inthe wll honing andinside flushing under the high pressure- antirust oiling outside surface- plastic coaapin on both ends.

main features

high precision, excellent brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness ofinside wall, the steel tube is able to withstand high pressure, no deformation afer cold bendingm no crack after flaring and flattening, the complicated geometrial forming and machining can be realized, color of tube, gray with wihite.

main application

to be used in hydraulic system, automobile and in the occasion where the high precision, brightness, cleanness and mechanical properties of the tube are required.
