Shower Room Door Handle Material: 304 vs 201

SHOWER ROOM SPECIALIZATION: 

This is a Shower Room Shower Door Handle accessory from Hydrorelax Whirlpool Parts Wholesale Manufacturer, which is suitable for most shower room systems.

Product features: The product is made of 304 S.S.(Stainless Steel) material, and the product surface processing technology is polished (Polished).

Product details: 

①Hole distance of installation: 10mm;

③Installation Center Distance: 200 mm or According to customer's requirements

Their nickel content and chromium content are different.

201:1Cr17M6Ni5N, indicating austenitic stainless steel 201 stainless steel containing 1% carbon, 17% manganese, 17% chromium and 6% nickel;

304: 0Cr19Ni9 (OCr18Ni9), indicating austenitic stainless steel 304 stainless steel containing less than 0.1% carbon, 18%/19% chromium and 9% nickel;

201 stainless steel contains manganese, in the air humid salt heavy maintenance it easy to oxidizes rust.

 (of course, much better than iron products and stainless steel oxidized rust can be brushed, polished, etc. to deal with again, unlike iron products like the surface of the plating layer of rust after no way to deal with it)

304 stainless steel does not contain manganese, chromium, and nickel, and it is not easy to oxidize rust.

201 stainless steel price is iron (chrome plating or painting furniture materials〉3-4 times the price of 304 stainless steel price than 201 stainless steel is more than half or nearly 1 time.

For cost and market acceptance considerations, most of the stainless steel furniture with 201 stainless steel, and only a small number of important parts are produced with 304 stainless steel.

In summary， the surface of 304 is with a metallic whitish luster, relative to 201 is like a plastic plate.

Stainless steel with its beautiful appearance, corrosion-resistant properties, and the advantages of not being easy to damage, is more and more people's favorite. Pots and pans, urban sculpture, construction, decoration of the living room, and other use of stainless steel more and more.

Iron-carbon alloys containing less than 2% carbon are called steel, while those containing more than 2% carbon are called iron.

Steel is widely used because it is tough, flexible, and rigid. Life in contact with is steel, but people call it differently. Stainless steel is stainless steel regardless of whether a magnet can absorb it or not, as long as it meets its quality standards. Therefore, from the metallurgical point of view, there is no such thing as stainless steel.

Steel with a chromium content of 10.5% or more is less likely to rust.

Different alloying elements are added during smelting, there is also a difference between the magnet can be absorbed and not absorbed.

If the steel is added to the different proportions of chromium and nickel, etc., refined austenitic steel is the magnet can not absorb the stainless steel; if the steel is added to the chromium and a small amount of nickel (or no nickel), refined steel is the magnet can be absorbed on the stainless steel, also known as the ferrite stainless steel; martensitic stainless steel main alloying elements are chromium, iron, and carbon. 

Stainless steel has more than 100 kinds of different alloy content. In addition to austenitic stainless steel, magnets can not be sucked, ferritic, and martensitic stainless steel are magnetic.

The element nickel has very few reserves in the world and is relatively expensive. 

Therefore, stainless steel with high nickel content is also more expensive in the market, and the magnet can't absorb it.

There is a kind of stainless steel magnet that can not be sucked. That is high manganese containing less nickel or nickel-free stainless steel. This stainless steel market price is higher than the nickel-containing stainless steel per ton of low 1000 yuan. 

Some dealers are using people's "good stainless steel magnets can not be sucked" misunderstanding, to deceive consumers, the price of stainless steel with high nickel content is expensive.

Generally do decorative, landscape, and sculpture selection of austenitic stainless steel. 

Because of the austenitic stainless steel's low thermal conductivity, with it to do the kettle, frying pan, and rice pan are not suitable, will use a lot more energy, and also extend the time for boiling water cooking. 

Ferritic stainless steel frying pans, and rice pans, not only have excellent corrosion resistance, but their thermal conductivity than austenitic stainless steel is nearly half. 

Washing machine barrel, water heater, wash basin, etc., as long as the utensils in contact with water should be selected ferritic stainless steel. 

Some people complain that stainless steel knives are not fast, this is because of the wrong choice of stainless steel. Austenitic stainless steel can not be hardened, not suitable for knives, or cutting tools. 

Knives made of martensitic stainless steel can be heat-treated, such as quenching and tempering to change the hardness of stainless steel.
