Roll hanging out and being friends with Snake Man (request from anon from a looooong time ago)

[akaluan]

Hm. Well then. Trails to Azure sure ends on a downer note, looooool

Like, hey, glad you achieved the goal you were aiming for. Glad you saved your little girl, I too am attached to her, she's adorable.

Unfortunately you are but eight random people who, for the most part, have no pull outside of your little bubble. Now suffer the consequences of the political powderkeg that exploded while you watched helplessly.

Cheers, looking forward to seeing you again after a minimum two years of Shit Gone Fucked Up

Hot Rolled vs. Cold Rolled Steel: Unveiling the Key Differences for Optimal Performance

In the world of steel manufacturing, understanding the differences between hot rolled and cold rolled steel is crucial for selecting the right material for your projects. Each type offers unique properties and benefits that cater to different applications and performance requirements. This article will delve into the key differences between hot rolled and cold rolled steel, helping you make informed decisions for your needs.

For high-quality steel products and more information, visit Stainless Steel Strip Coil.

What is Hot Rolled Steel?

Hot rolled steel is produced by rolling the steel at high temperatures, typically over 1700°F (926°C). This process makes the steel easier to shape and form, resulting in a product that is ideal for structural components and other applications where precise shapes and tolerances are less critical.

Characteristics of Hot Rolled Steel

Surface Finish: Hot rolled steel has a rough, scaly surface that is a result of the cooling process after being rolled.

Tolerances: It generally has looser tolerances compared to cold rolled steel, making it suitable for applications where exact dimensions are not crucial.

Cost-Effective: The production process is simpler, making hot rolled steel more cost-effective for large-scale manufacturing.

Ductility: It has excellent ductility, allowing it to be easily welded and formed into various shapes.

What is Cold Rolled Steel?

Cold rolled steel is produced by rolling the steel at room temperature after it has cooled from the hot rolling process. This additional processing step enhances the steel's strength, surface finish, and dimensional accuracy, making it suitable for more precise and high-performance applications.

Characteristics of Cold Rolled Steel

Surface Finish: Cold rolled steel has a smooth, polished surface that is aesthetically pleasing and ideal for visible components.

Tolerances: It has tighter tolerances and greater dimensional accuracy, making it perfect for applications that require exact specifications.

Strength: The cold rolling process increases the steel's strength and hardness, providing better performance in demanding environments.

Cost: Due to the additional processing steps, cold rolled steel is typically more expensive than hot rolled steel.

Key Differences Between Hot Rolled and Cold Rolled Steel

Manufacturing Process

Hot Rolled Steel: Rolled at high temperatures, which allows for easier shaping but results in a rougher finish.

Cold Rolled Steel: Rolled at room temperature, providing a smooth finish and greater strength due to the additional processing.

Surface Quality

Hot Rolled Steel: Rough, scaly surface that is suitable for structural applications where the finish is not a primary concern.

Cold Rolled Steel: Smooth, polished surface that is ideal for applications requiring a high-quality finish.

Dimensional Accuracy

Hot Rolled Steel: Looser tolerances, making it suitable for projects where exact dimensions are not critical.

Cold Rolled Steel: Tighter tolerances and greater precision, ideal for high-performance applications.

Cost

Hot Rolled Steel: More cost-effective due to the simpler manufacturing process.

Cold Rolled Steel: More expensive due to the additional processing and improved properties.

Applications of Hot Rolled and Cold Rolled Steel

Hot Rolled Steel

Construction: Used for structural components like I-beams, angle iron, and other infrastructure.

Automotive Frames: Suitable for parts that do not require precise dimensions.

Heavy Equipment: Ideal for manufacturing components that will undergo further machining or fabrication.

Cold Rolled Steel

Precision Parts: Used in manufacturing parts that require tight tolerances and high strength.

Appliances: Suitable for making components that need a high-quality finish and precise dimensions.

Automotive: Used for manufacturing critical components that require greater strength and accuracy.

Conclusion

Choosing between hot rolled and cold rolled steel depends on your project's specific requirements. Understanding the key differences in their manufacturing processes, surface qualities, dimensional accuracies, and costs can help you make an informed decision.

Rock and Roll personality swap for @craftycake277world ‘s art prompt

So like, AU where everything is the same but Roll is the reserved, science-loving twin chosen to become the bomber robot hero while Rock is actually into Rock music and is the tagalong with the homemade utility arm, hahaha

Trying to find the right way to phrase "Kiseki/Trails lost its edge at some point during the Cold Steel games" to indicate that it is literally less edgy, considering that nearly everyone- including several antagonists- reacts to one airship with three people on it getting blown up like it's the most horrific warcrime committed in the history of civilization.

It's not necessarily a bad thing because I'm still fully invested in the game, but it's just weird to go from Azure, which had no qualms about showing Bloody Shirley gleefully murdering a bunch of ILF members and gleefully crippling a woman to her reacting to one airship with three people on it blowing up like "woah... this is too much even for me..."

Stainless Steel 904L Sheets & Plates Manufacturers in India

Stainless Steel 904L Sheets & Plates

Stainless Steel 904L Sheet is a super austenitic stainless steel that is created for moderate to high corrosion resistance in a wide range of environments. The mixture of chromium and nickel content, with the additions of molybdenum and copper, provides excellent corrosion resistance. Due to nickel 25% and molybdenum 4.5%, B625 UNS N08904 provides good chloride stress corrosion cracking resistance, pitting, and general corrosion resistance which is superior to 904L and 317L. It is developed to out-break environments containing dilute sulphuric acids. Stainless Steel 904L plate has good resistance to inorganic acids such as hot phosphoric acid. It can be easily welded and processed by a standard fabrication process.

Stainless steel 904l plate is quite ductile and can be easily formed. The addition of molybdenum and nitrogen provides more powerful processing equipment and it may be necessary when compared to the standard 304/304L grades. A240 type 904l has excellent resistance to warm seawater and chloride attack. The high resistance of it is against stress corrosion cracking and it is due to the presence of high amounts of nickel in its composition however, the structural stability of this grade collapses at high temperatures, particularly above 400°C. A240 UNS N08904 material can be solution heat-treated at 1090 to 1175°C by following by rapid cooling method. Thermal treatment is suitable for hardening it. 1.4539sheet major applications are oil refinery equipment, Pulp, and paper processing industries, gas scrubbing plants, etc.
