I have found through experience that hot rolled steel will take 95/5%
solder, and that cold rolled will not solder, reason is the cold rolled steel molecules are arranged differently that the hot roll, they are so to speak pushed into the final dimension with extreme pressure this also causes
a so called hardened tempered surface on the cold roll steel that has to be annealed so that it can be drilled. cut or soldered.
It will solder, braze, and weld easily. Just be sure it is clean (bare metal), and you have all the usual requirements which are; enough heat, correct flux and solder. Nothing special about steel, cold rolled or otherwise.
No, cold-rolled steel should not be soldered. Scale, rust, or other contaminants commonly coat cold-rolled steel, making it difficult for solder to adhere properly. Furthermore, cool moved steel has a higher liquefying point than most fastening combinations, making it hard to accomplish major areas of strength for a. When joining cold rolled steel, it's best to use alternative methods like welding or brazing because they give better results in terms of strength and durability.
The cold-rolled steel's surface properties can make it difficult to solder. The smooth and frequently coated surface of cold-rolled steel can make it challenging for solder to adhere properly. Cold-rolled steel may also have an oxide layer that makes soldering even harder. It is by and large prescribed to pre-treat the surface by cleaning and roughening it to work on weld attachment. Additionally, the process of soldering can be aided by employing a steel-specific flux. However, it is essential to keep in mind that soldering may not be as effective at joining cold-rolled steel as welding or brazing.

Difference between Black mild steel and bright mild steel?
from what i can gather, which isn't alot:Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills.Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale. The surface is then washed to remove the acid and a light oil added to prevent rusting.Mild steel sheet is manufactured generally in two grades, cold rolled and hot rolled.Hot rolled mild steel sheet is the initial product produced by the steel mill as a downstream process prior to further processing such as cold rolling.Hot rolled mild steel sheet has a mill scale which is usually black in colour. Hence the common name Black Mild Steel Sheet. Black mild steel sheet is commonly used in fabrication shops, it is more economical than cold rolled mild steel sheet.Black mild steel sheet will usually require more preparation work prior to any finishing system being applied.Cold rolling is done to:Reduce the thicknessImprove the surface finishImprove the thickness tolerancesTo offer a range of "tempers"As a preparation for surface coating
Describe and explain the steel production?
When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable. To become steel, it must be melted and reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. This liquid is then continuously cast into long slabs or cast into ingots. 96% of steel is continuously cast, while only 4000 ingots are cast per year. The ingots are then heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. In modern foundries these processes often occur in one assembly line, with ore coming in and finished steel coming out. Sometimes after a steels final rolling it is heat treated for strength, however this is relatively rare. Hope this helped
What is the full form of C.R.C pipes?
Cold Rolled Coil Pipes
What is a Mill Certificate?
A mill certificate can be a steel industry document that is used to certify the manuafacturing standards of the products produced by the mill. It can specify the following: A recognized Standard specification number such as an ASTM or AISI number (Ex ASTM A106. The ASTM is the American Society for Testing and Materials. This identifies the type of product (sheet, plate, tube, bar, etc.) and the set engineering standards to which it is produced. An analysis of the elements (%) that make up the content of the mill product. Ie. carbon, nickel, titanium. Brief description of the goods such as galvanized carbon steel sheet, welded tube, seamless pipe, zinc coated, hot rolled or cold rolled plate, etc.
What is the difference between blooms and billets in a steel industry?
Bloom : A semi-finished long product of greater than 150 mm square or rectangular cross-section. Blooms can be produced by continuous casting or by rolling from ingot. Continuously cast rounds of 300mm diameter or greater are also referred to as blooms.Billet : A semi-finished long product of up to 150 mm square cross-section with round corners. Billets can be continuously cast or hot rolled from either ingots or larger concast billets and blooms. They are re-rolled or forged into other formsFor More Details Plz Visit at: steelmkts.com (Like, Ms Ingot, Scrap, Sponge Iron, Pig Iron, TMT, Rebars, Iron Ore, Wire Rod, Angle, Channle, Girder, HR/CR Coils, Billets, Iron Pellets, Rolling, Metals,etc. Prices) OR Call +91-98888-14974Iron & Steel Price in Mandi Gobindgarh, Steel & Iron Prices Of Ludhiana, Iron & Steel Prices in Mumbai, Steel Prices in Maharashtra, Steel & Iron Prices of Jammu, Iron Prices of Kolkata, Steel & Iron Rates in Durgapur,Steel & Iron Rates in Bangloure, Steel & Iron Rates in Bhavnagar, steel price in Tamil Nadu, Steel & Iron Prices in Chennai, Iron Price in Ahmedabad, steel price of Alang, Iron rates of Ghaziabad, Steel & Iron Price in Hydrabad,steel prices of Jaipur, Iron and Steel Prices in Bhiwari, steel price of Mujaffarnagar, iron & steel Rates in Raipur, iron prices of Rourkela, steel prices in Raigarh, Steel Prices of Nagpur, Iron & steel prices in Orissa
What is ST 37 hot rolled or cold rolled steel?

What is Cold rolled ganvanized steel?
Steel which has been rolled out at temperatures below red heat, and then coated with zinc.
What is the Hs code of cold rolled steel coils?
In order to help you classify your product, I will need further clarification. Do you mean "cold rolled steel, in coils" or "coils made of steel"?
What are CRGOS steel sheets?
Cold Rolled Grain Oriented Silicon steel sheets
Is cold rolled harder than hot rolled steel?
They are two different things. Zinc plated means it's coated in zinc. Cold rolled means it's "smashed" into shape without added heat. So you could have something that's cold rolled AND zinc plated!
