1.Structure of Stainless Steel Coil Cold Rolled 304 With Good Quality
Cold Rolled stainless steel Coil with good quality is one of the raw material of the cold
rolled stainless steel Coil, which can be used directly in many places. Stainless Steel
(Stainless Steel) is short for acid-proof Stainless Steel, resistant to weak corrosive
medium such as air, steam, water, or with a Stainless Steel grade.
2.Main Features of Prefabricated Steel Structure High Building Project
Weld-ability: The purpose of the different requirement for welding performance are
different.1 Kind of tableware generally do not require the performance of welding, even
including some pot class enterprise. But the vast majority of products all need raw
materials welding performance is good, like the 2 kinds of tableware, thermos flask, steel
pipes, water heaters, water dispensers, etc.
Heat resistant performance Heat resistant performance refers to the high temperature
stainless steel can still maintain its excellent physical and mechanical properties. Carbon:
the influence of carbon in austenitic stainless steel is formed strong and steady. Set the
austenitic austenitic area and expand elements. Carbon formation of austenite is about 30
times that of the nickel, the ability of carbon is a kind of gap elements, through the solid
solution strengthening can significantly increase the strength of the austenitic stainless
steel. Carbon austenitic stainless steel can be improved in high concentration chloride
(e.g., 42% MgCl2 boiling solution) in the performance of the resistance to stress corrosion.
But, in the austenitic stainless steel, carbon is often seen as the harmful elements, this is
mainly due to the corrosion of stainless steel used in some conditions, such as welding or
heating by 450 ~ 850 ℃), carbon steel with chromium in forming high chromium Cr23C6
type carbon compounds which can lead to local chromium depletion, make steel corrosion
resistance especially resistant to intergranular corrosion performance degradation. So.
Since the 60 s of the development of new Cr-Ni austenitic stainless steel is mostly carbon
content less than 0.03% or 0.02% of the ultra-low carbon type.

4. Stainless Steel Coil Cold Rolled 304 With Good Quality Specification
Ferritic stainless steel Chromium containing 15% ~ 30%. Its corrosion resistance,
toughness and weldability with chromium content increases with the increase of chloride
stress corrosion resistance is superior to other types of stainless steel, fall into this
category of Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28, etc. Ferritic stainless steel because
of the high chromium content, corrosion resistance and oxidation resistance are relatively
good, but the mechanical properties and process performance is poorer, more used to
stress less acid structure and steel used as antioxidant. This kind of steel to withstand
atmosphere, nitric acid and corrosion of the brine solution, and has good high temperature
oxidation resistance, low thermal expansion coefficient, etc, used in nitric acid and food
factory equipment, also can make work under high temperature parts, such as gas turbine
parts, etc.
Austenitic, ferritic duplex stainless steel The advantages of both austenitic and ferritic
stainless steel, and has the superplasticity. Austenite and ferrite The title Each accounts
for about half of the stainless steel. In the case of contain low C, Cr content was 18% ~
18%, Ni content at 3% ~ 3%. Some steel containing Mo, Cu, Si, Nb, Ti, N and other
alloying elements. This kind of steel both austenite and ferrite stainless steel, the
characteristics of compared with ferrite, plasticity and toughness is higher, no room
temperature brittleness, intergranular corrosion resistance and welding performance were
significantly increased, while maintaining a ferritic stainless steel of 475 ℃ brittleness and
high thermal conductivity, has the characteristics of superplasticity. Compared with
austenitic stainless steel, high strength and resistance to intergranular corrosion and
resistance to chloride stress corrosion is improved obviously. Duplex stainless steel has
excellent resistance to pitting corrosion performance, is also a kind of nickel and stainless
steel.
