Other 409 silicon steel grades representation

(1) cold-rolled non-oriented silicon steel strip by the nominal thickness (enlarged 100 times the value of) A + + code to ensure that the iron loss value (frequency stainless steel magnetic‍, the maximum flux density of iron loss value expanded 100-fold when the 1.5T) . If 50A470 represents the thickness of 0.5mm, iron loss guarantee value ≤ 4.7 cold rolled non-oriented silicon steel strip. (2) Cold-rolled grain oriented silicon steel with the nominal thickness (enlarged 100 times the value) + Code G: said common materials, P: indicates highly oriented material + iron 1.4016 steel 2r‍ loss guaranteed (the frequency 50HZ, the maximum flux density of 1.7T when the value of iron loss value after 100 times enlarged). If 30G130 represents the thickness of 0.3mm, cold-rolled iron loss guarantee oriented silicon steel strip is ≤ 1.3.

The SPCE series stainless steel coil

SPCE - expressed deep drawing cold rolled carbon steel sheet and strip, equivalent to China 08AL (5213) deep drawing steel. The need to ensure non-aging, the increase in grades at the end of N is iron 1.4301 steel coil 2r finish‍. Cold-rolled carbon steel sheet and strip quenched Code: annealed state A, the standard quenching of S, 1/8 hard to 8,1 / 4 hard to 4,1 / 2 Hard 2, the hard one. Surface processing stainless steel supplier‍: matt finishing is D, bright finishing as B. SPCC-SD represents the standard quenched, rolled carbon sheet matt finishing. Again SPCCT-SB represents the standard conditioning, bright processing, required to ensure the mechanical properties of cold-rolled carbon sheet.

430 stainless steel (including steel) Classification:

4, according to use classification
(1) bridge Cold rolled stainless steel (2) boiler plate (3) shipbuilding steel plate (4) armor plate (5) automotive steel (6) roof plate (7) Structural Steel (8) electrical steel (silicon steel) (9) spring steel (10) the other two, general and mechanical structure with steel grades are common

430 series stainless steel plate JIS

Grade steel (JIS series) of the general structural steel material of said first portion mainly composed of three parts, such as: S (Steel) said steel, F (Ferrum) represents iron; the 304 stainless portion of said different shapes, types, uses, such as P (Plate), said plate, T (Tube), said pipe, K (Kogu) said tool; third part of that feature figures, usually a minimum tensile strength. Such as: SS400 - S represents the 304 stainless steel plate steel (Steel), said second S "configuration" (Structure), 400 to lower the tensile strength of 400MPa, a tensile strength of the overall means of ordinary structural steel 400MPa.

stainless steel coils internal organizational structure - Chromium

In order to ensure the yield strength of various types of stainless steel coil, the mechanical properties of tensile strength, elongation and hardness to stainless steel sheet the requirements, you must go through annealing, solution treatment, aging heat treatment prior to delivery of stainless steel coil. The corrosion resistance of stainless steel coil depends primarily on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal organizational structure of stainless steel coils, played a major role in chromium. Chromium has a high chemical stability, steel magnetic stainless steel film formed on the surface of the metal with the outside world to isolate and protect steel from oxidation, increasing corrosion resistance of steel. After the destruction of the passive film, corrosion resistance decreased.

Introduction 409 stainless steel plate stainless steel tube

Stainless steel pipe: seamless and seamed pipes (Longitudinal, decorative pipe, welded pipe, pipe, light pipe) .409 stainless steel plate 200 kinds of standard, size has a stainless steel 410 tube is more expensive, especially the capillary capillary worst production from the 304, or burst pipe easily. also custom-designed non-standard specifications of the pipe. seamless mainly used for industrial, surface matte, not shiny. seamed tube surface is bright surface, there is a very thin tube welding line, commonly known as welded pipe, mainly used for stainless steel 430ba materials, and another industrial fluid tube wall thickness of the decision as anti-stress and 310S for the heat pipe .310 .1080 degrees below normal use, maximum temperature of 11.5 degrees.
