Product Specifications:

 

Spring Steel can be divided into two types. One is carbon spring steel, and other one is alloy spring steel.

Alloy spring steel is based on carbon spring steel, by adding one or more alloying elements to improve the mechanical properties, hardenability and other properties to meet the requirement for manufacturing all kinds of spring steel.

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: Can stainless steel rust?

A2: 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:Cold rolled flat steel standard. What is cold rolled flat steel?
Flat steel, width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Section steel is one of the four major steel products (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..
Q:Do I need to make the ring galvanized flat steel ground connection between the electric well and the distribution room?
There is also a dark, in the foundation of the house to consider the distribution of indoor total potential imbalance, in the basic reinforcement welding has been laid. Later, when installing the equipment, just connect in place
Q:The steel, steel and flat steel, round steel bar and what is the difference?
There is not much difference between round bar and steel bar, but the diameter range should be different. Can you hold it with hand?Inside the details of the difference, you can go to the tool book to see.
Q:How is three grade steel connected to ground flat steel?
HRB400 can be directly welded by hand arc welding with Q235 flat steel into electrical circuit. (I have done two sets of tensile tests last year, qualified).
Q:Why is it better to use round steel than that of flat steel in lightning protection?
In the construction of lightning protection, both round bar and flat steel have different uses. Flat steel is generally suitable for horizontal connection between vertical grounding poles for lightning protection. Round steel is suitable for lightning protectionThe guiding line and connected with lightning. The roof, all of the junctions are connected by welding requirements do not exist, what striking issues... The technical norms of the state said so, does not have what good and bad problem
Q:What is the use of slitting flat steel?
Flat cut flat steel, also called fine shearing flat steel strip, can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.
Q:The grounding electrode 50 angle steel and the ground wire 50, the flat steel lap welding, according to the specification 169 needs the flat steel to be late 90 degrees, bends close to the angle steel side, the overlap width is 4 times (200mm)?
GB50169-2006 in the 3.4.2 stipulates that the grounding body (line) shall be welded by lap welding, and its lap length shall comply with the following requirements:1. flat steel is 2 times its width (and welded with at least 3 edges);2. round steel is 6 times its diameter;3. round steel and flat steel connection, its length is round steel diameter of 6 times;
Q:What is the appearance of hot galvanizing and cold galvanized flat steel?
The appearance of cold plating smooth point heat plating, there is also the difference between the two prices, if the project budget it is recommended to use a hot dip, if it is hot for outdoor plating relatively easy to rust, cold plating used in outdoor it is easy to rust, the appearance is not good, relatively Engineering the quality will also be questioned, if you can use the indoor cold plating, can save a lot of budget
Q:Is medium plate steel flat?
Medium and heavy steel plate is mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc.. Can also be used to manufacture all kinds of containers, furnace shell and plate, bridge and vehicle static steel, low alloy steel plate, ship plate, boiler plate, pressure vessel steel plate, embossed steel plate, steel plate for automobile frames, tractor parts and some welding components etc.. Through the plate uses: widely used in the manufacture of various containers, furnace shell and plate, bridge and vehicle static steel, low alloy steel plate, bridge plate, boiler plate, steel plate, a pressure vessel steel plate, embossed steel plate, steel plate for automobile frames, tractor parts and some welding component application.
Q:What is the representation of flat steel?
In use, it has advantages over steel platesFlat steel adopts negative deviation rolling, but according to actual weight, the utilization ratio of steel plate is 1~5 percentage points higher than that of steel plate.Flat can according to user needs, set the thickness, width and length of production, for the user to reduce the cut and save processes, reducing labor, material consumption, but also reduce the loss of raw materials processing, time saving, material saving. Products have been specialized in steel structure manufacturing, machinery manufacturing, automotive industry, mining machinery, lifting machinery and other industrial materials.
