Product Specifications:

Spring steel is divided into two types, one is alloy spring steel, and other one is carbon spring steel.

Alloy spring steel is a type that is used for manufacturing springs and other elastic parts. Spring steel should have high elastic limit and ratio of yield strength and tensile strength to make sure that the springs obtain enough power of elastic deformation and can bear much load.

Types of alloy spring steel: Si-Mn spring steel, Si-Cr spring steel, Cr-Mn Spring steel, Cr-V spring steel and so on.

Usage/Applications of Spring Strip Steel:

-Due to the elements W, Cr and V, this type of spring steel obtain pretty high hardenability and nice mechanical properties under room temperature and high temperature. The tempering stability and hot workability are good.

-Being used under the state of quenching and high temperature tempering. It’s usually used as heat-resisting springs with working temperature below 500℃, like main secure valve spring of furnace and turbine steam seal leaf springs.

 

FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: How do we guarantee the quality of our products?

A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q4: What makes stainless steel stainless?

A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q5: Can stainless steel rust?

A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:What is the hardness of cold rolled steel strip?
Generally, the Rockwell hardness of annealed carbon steel is 55+-3, and the hardness of annealed cold rolled strip is above 80
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Roll, roll grinding after due to severe pressure, taper, makes the school not to the operator in the rolling process of double pendulum regulation increases taper, will cause serious side light waves caused by shape defects, cause strip deviation and broken belt.
Q:What are the high speed steel strips and material specifications?
(1) main usesUsed for stamping machine parts, metal products and manufacturing structural parts, etc..(2) the grade and chemical composition of the materialIn line with GB699 (high-quality carbon structural steel technical conditions), the brand is 15-70# steel provisions.
Q:Where is the lining board made of polyurethane lining? Please contact immediately
Selection of raw materials: different polyol raw materials with different molecular structures and molecular weight, the performance gap between different polyols, the use of the environment and the requirements are not the same, each with unique characteristics and optimum application. Polyester polyol, wear resistance, corrosion resistance, good oil resistance, high mechanical strength, good aging resistance. Polyether polyols have good resilience and low temperature compliance, and they also have good hydrolytic stability and mildew resistance. There are many curing agents, and different formulation systems use different performance requirements. The choice of different systems depends not only on the performance requirements of the product, but also on the price of the product. The abrasion resistance of the wear-resistant lining plate is determined by the raw material chosen.
Q:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
Cold rolled coil (annealed): hot rolled coil obtained by pickling, cold rolling, batch annealing, flattening, and finishingThat is, the biggest difference between hot rolled coil and cold rolled coil is that the heat treatment process is different. (annealing process)Compared to the specific heat roll, the cold-rolled roll has a bright surface and a high degree of finish, but it produces more internal stress and is often annealed after cold rolling.
Q:What is the difference between steel strip and strip steel?
The steel strip is the product which the processing enterprise cuts the strip steel according to the specific machine size to cut into a certain length, the width, generally assumes the enclosed circle shape. For example, steel conveyor belts, such as furniture or wood processing enterprises, "band saw" saw blade, but also steel band.
Q:What is cold rolled strip and hot rolled strip? Why is it called strip steel?
When the cold rolled steel strip is processed and shaped, the raw material is made at the normal temperature, so the mechanical properties of the steel strip are crisp and hard and have good elasticity.
Q:Steel industry, strip 195, where can strip be used?
Rolling sheet and wire rod for cold and hot rolling thin steel plate and its original made of zinc, tin and plastic made from composite sheet for roofing plate, decorative board, general pipeline, container, railway, instrument shell, switch box, protective cover, train etc.. Wire rod is more cold drawn into low carbon steel wire, light galvanized goods, made of galvanized low carbon steel wire, used to tie the tension fixed goods, used as steel wire mesh, rivets and so on. I hope my answer is satisfactory to you!
Q:What's the cutting edge of cold rolling strip?
Do you mean the cutting edge is the indication of the steel roll out of the factory? When the steel factory leaves the factory, the steel coil will have the burr and the cutting edge two kinds, the rough edge is the steel strip two, the edge is not neat. The trimming is the two sides of the steel band, and the width of the strip is certain when it is trimmed.
Q:1 can thick galvanized steel square pipe burn welding?
Welding can only use 2.5 of the electrode, the current transferred to 80A, slowly welding, yes, I have also welded. If the line is conditional, do better with sub fluorine welding or oxygen welding.
