Ishmael strip stainless AISI304, aluminum strip (tire) AD31, D16T, cutting and delivery
The strip corrosion-proof is a high-quality metal rolling which in a form reminds a steel strip of a rectangular shape. The dimensions of the stainless steel tape are regulated by the requirements of GOST and include such parameters as: length, width and thickness.
Advantages
Stainless steel strip has gained its popularity due to the following advantages:
flexibility;
temperature resistance;
environmental friendliness;
interaction with chemicals in an aggressive environment;
rust protection;
long service life;
aesthetic look.
Production
A stainless steel strip is produced according to GOST standards from steel of different grades by hot or cold rolling on a mill. Additionally, the tape is subjected to polishing, grinding, corrugation, metallization and even drawing on one side. Depending on the characteristics of the processing of the product, the tape can be: cold-worked, semi-hard-worked, highly-worked and soft. According to the characteristics of the composition of the steel from which the strip is made, products with the addition of chromium, nickel and manganese are distinguished.
Assortment
There are several parameters by which stainless steel tape can be classified.
So, according to the type of surface treatment, a stainless strip is:
polished;
mirror;
matte.
According to the texture, the surface of the stainless steel tape can be:
perforated
corrugated
decorative
By scope, there is a band:
spring
food
packaging
bandage
assembly room
According to the accuracy, the stainless strip is divided into three classes:
High accuracy class - "B";
Increased accuracy class - "A";
Normal accuracy class - "B".
For the main purposes in construction and production, a stainless strip of normal or normal accuracy is used. Under conditions of increased load, other types of it are used, with improved characteristics.
Band sizes can also vary. Depending on the scope of the metal-rolling material, strips are produced with the following parameters: strip thickness can be from 2 to 80 mm, width from 15 to 200 mm, length from 3 to 12 m.
The classification according to the purpose of the length is the same as that of the ordinary steel strip:
Measured length;
Multiple measured length;
Unmeasured length.
The degree of curvature of the strip is determined by two classes. The crescent of the stainless strip can be no more than 0.2% of the length of the strip, this type belongs to the first class of stainless steel. The second class of stainless steel strip is determined by the crescent not exceeding 0.5% of the strip length.

Main properties of stainless strip
Stainless steel strip has a number of advantages over other flat products. Chromium, the material that is the main material in the production of the strip and gives it such properties. It is contained in steel in the amount of 12-20% and above. Namely, the presence of chromium in the composition of stainless steel gives the alloy itself and products made from it high anti-corrosion properties and resistance to various aggressive environments.
Also, the stainless strip, or rather stainless steel, from which it is made, includes carbon, silicon, manganese, sulfur and phosphorus. To give the metal the required physical and mechanical characteristics and greater resistance in various aggressive environments, titanium, nickel, niobium, cobalt, and molybdenum are also added.
Stainless steel strips differ in composition:
Chrome stripes;
Chrome-nickel;
Chrome-manganese-nickel.
Stainless steel strip is made from heat-resistant and corrosion-resistant alloys. The grade of the alloy has its own designation in the form of letters and numbers. The letters show the main components included in the alloy. The numbers indicate the percentage of this element in the steel alloy.
The main alloying components of the stainless steel alloy and their marking:
Nickel - "H";
Titanium - "T";
Chrome - "X";
Molybdenum - "M".
The number of these elements depends on the steel grade produced in accordance with state standards.
The most common heat-resistant alloys from which steel is made. stainless strip:
Nickel-containing - 12X18H10T, 20X23H18, 08X18H10T, 10X17H13M2T;
Without nickel - 20X13, 95X18, 40X13, 15X25T.
There are many other stainless alloys, but they are less well known.
Why choose stainless steel strip?

The stainless strip is quite popular in the metal-roll market, has a wide range of applications and is sold at a relatively affordable price. Before deciding on the choice of ordinary steel or stainless steel, it is worth considering the characteristics of the stainless strip. Such a strip has a number of positive qualities:
It can be used in places where both low and high temperatures are affected, because the strip has a high resistance to temperature, so the service life will not change;
If the band are supposed toexposure to alkaline, acid and any other aggressive environment, stainless steel strip will withstand any such load, its anti-corrosion properties are superior to any other steel strip;
The stainless strip goes well with other materials;
Possesses high properties of fire safety;
It has an aesthetic appearance, so it can be used in architecture, blacksmithing, etc.;
Surprises with its versatility. With such high characteristics of strength, flexibility and durability, stainless steel strip can be used in all fields of construction and industrial production;
The possibility of welding and manufacturability makes it possible to produce both simple and complex parts from stainless steel strip;
Stainless strip products are intended for use in normal conditions, outdoors and with increased corrosive influences.
The use of stainless steel strips.
The stainless strip is resistant to rust formation under environmental conditions, has a long service life. Therefore, stainless strips are used for the manufacture of metal structures, as well as for the production of bent profiles, cutting tools, springs and other products. Often, a stainless steel strip is also used to decorate arches, columns, etc.
Surface types of stainless strip.
There are many ways to process stainless strips to give their surface the qualities necessary for subsequent use. Hot-rolled (hot-rolled) stainless strips receive various types of surfaces during processing.
Depending on the brand of stainless steel strip and the presence of alloying additives in the composition, it is used for:
processing into shaped steel - pipes, angles, channels. The shape and profile are formed by passing the strip through rolling rolls;
production of industrial equipment that is operated in conditions of elevated (low) temperatures or aggressive environments;
production of household appliances, equipment in the medical and food industries with high requirements for hygiene and environmental friendliness of the material;
tooling production in construction, sea and railway transport;
architectural solutions and the manufacture of outdoor and facade decor.
Stainless steel is well welded, easily machined, chemically inert to acids, alkalis and can be used in conditions of high humidity and critical temperatures. Fire safety and chemical inertness allows the use of stainless strip in the manufacture of instruments and equipment for the oil refining and chemical industries.
