Product Description:

One, introduction

Hot rolled coil is used for continuous casting slab or slab as raw material, after reheating furnace heating, scales entered the roughing mill in the high pressure water, roughing cut is expected by the head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling, finally after rolling through the laminar cooling (computer controlled cooling rate) and coiling machine coiling, become straight hair volume. Hair straightener roll head, tail often forms a tongue shape and fishtail, thickness, width of poor accuracy, edge has wavy, folding, tower and other defects. The volume weight heavier, steel coil diameter is 760mm. (general pipe industry like use. )

2 two, characteristics

Because there is no after annealing treatment, the hardness is very high (HRB greater than 90), mechanical processing performance is poor, only a simplebending process has less than 90 degree directional (direction perpendicular to the rolled).

Three, use 3

Hot rolled products with high strength and good toughness, easy processing and good forming can be excellent performance of welding, which is widely used in ships, cars, bridges, buildings, machinery, boiler, pressure vesselmanufacturing industry.

The scope of application:

(1) after annealing processing into the common cold;

(2) processing galvanized galvanized unit before the annealing treatment;

(3) the basic do not need to process the panel.

4 four, classification

Carbon steel plate, carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate etc.. Rolling hard volumes: under normal temperature,the hot pickling volumes of continuous rolling.

Hot rolled steel strip products include steel (roll) and the shear of steel plate.And steel (coils) can be divided into straight and finishes volume (the volume,smooth rolling and slitting roll).

Q:Are steel strings bad/hard for a beginner?
Best way to build calluses and finger strength. I am assuming that you are looking at an acoustic guitar. Buy Martin Phosphor Bronze 12s or 13s. Not to mention Classical guitars that use nylon strings usually have a very flat radius to the fingerboard thus making it harder to reach common chords for a beginner. DO NOT learn on an electric.
Q:Questions about Steel. Please Help?
It is usually a grey color, more silver when freshly scratched. Every one of the other questions can range based on the quality of the steel and other variables such as thickness. That's more than likely the reason you couldn't find any info on it. Its hardness is based on quality, for example regular steel is softer than Mild steel. It can be a thin sheet or a thick plate (which could then be changed to a tube Circle or square) etc
Q:how to make a steel helmet?
The okorder.com (Artist Blacksmiths) or on the sites of the two organizations that reproduce old costumes and tools - one is called The Society for Creative Anachronism, not sure of the other. Search terms to use might be hammering a helmet and forging medieval armor
Q:what is stainless steel?
Nickel, Chrome, others... [edit] To make ASTM A182A F316 (regular forged stainless steel), the required percentages are: 0.08%____Carbon 2.00%____ Manganese 0.045%___ Phosphorus 0.030%___Sulfur 1.00% ___Silicon 10-14%___Nickel 16-18%___Chromium 2-3%_____Molybdenum Heat treat - solution treat and quench Austenitizing/Solutioning Temp (min) - 1900°F Cooling media - liquid Quenching cool below 500°F The addition of chromium is (mostly) what makes it stainless... the other alloying elements provide it with other characteristics - toughness, weldability, temperature resistance, etc...
Q:Is stainless steel magnetic?
Some stainless steel are magnetic and some aren't. The real high grade stainless steels aren't magnetic.Stainless is just regular steel with varying degrees of nickel and chromium alloys mixed in the batch. The more nickel and chromium the less likely to be magnetic. A lot of stainless exhaust pipes and barbecue grills claim to be stainless, and yet they still rust and tend to be magnetic. They must use the bare minimum of nickel and chromium in the melted batch just to claim the title of stainless steel. Nickel and chromium are quite expensive and they are what gives the steel the anti-corrosion and extreme hardness characteristics along with loss of magnetism of the steel. If you have stainless steel that is magnetic , it is a good sign it is stainless steel that barely meets the criteria of true stainless steel.
Q:Steel braided fuel, air, and coolant lines?
Very good idea depending on the application. The steel braid reinforces the rubber to make it withstands pressure. Example, pressure side of power steering pump is reinforced, the return side doesn't usually need to be. Carbed cars usually run around 3-7 lbs on fuel line so no need, fuel injected cars run roughly 45 psi and up usually so those are braided.
Q:why do ships of steel float?
They okorder.com/... Or use the search bar*. (The question has been answered a thousand and one times). If you do then you will read many answers that push the popular myth that they displace more water than they weigh (as if some unseen 'finger of god' is supplying a mystery force in addition to the vessel's weight). Such 'explanations' cannot be supported by either calculation or experiment and are wishy-washy drively nonsense. So beware of Archimedes' Trolls on this one!
Q:steel refining process?
Refining process for steel include burning out the extra carbon and impurities with oxygen lancing and protecting the steel from atmospheric gas inclusion by protective environment during such process . Measured % of ferralloys are also added to produce various grades of steel . These may be done in induction furnace/ laddle refining furnace / crucibles converters etc.
Q:Titanium or Tool Steel?
I would have to say titanium , but in doing so I am having to assume you have access to some very serious machinery.This is because Ti is extremely difficult to work and also work hardens, which could lead to cracking and failure.The other problem is that Ti is also very hard to weld .It seems tool steel is the choice for ease of working and weldability, so unless you can buy the bits you need precut or made then I'd say tool steel,preferably something along the lines of ramax.Your other option is spring steel as this is workable and gets hardened after shaping.
Q:How would you encase steel in concrete?
Yeah, just pour the concrete over it, but make sure the steel is in the middle of the concrete (I'm sure you can figure out a way to do this). What you're thinking of is called steel rebar.
