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.
Q6: What is the difference between galvanized steel and Galvalume steel?
A6: Galvanized steel is metallic coated with Zinc in various coating weights. Minimum recommended for painted metal roofs is G90. Galvalume is a zinc and aluminum coated steel that becomes an alloy and is recommended in either painted or bare applications with a minimum coating weight of AZ50. Galvalume has an excellent performance life in bare exposures. Hence if you are using a bare panel use Galvalume and if painted use either.

- Q: How do steel coils contribute to the construction industry?
- Steel coils play a crucial role in the construction industry by serving as the primary raw material for a wide range of applications. These coils are used in the construction of buildings, bridges, highways, and other infrastructure projects. They are used to manufacture various structural components, including beams, columns, and trusses, providing strength, durability, and stability to the structures. Steel coils also contribute to the industry by enabling the fabrication of roofing and siding materials, reinforcing bars, and other construction elements. Their versatility, high strength-to-weight ratio, and resistance to corrosion make steel coils an essential resource for the construction industry.
- Q: The hard industrial steels. If there's a bunch, what's a rough average? Also, what is is measured in?
- There is no average, it depends on the type of steel (hundreds) and the (heat/surface) treatment (infinite possibilities). The Rockwell hardness range covers a large scale so for any given range there is a suffix (C is used for most steel) to denote the selected range. The number is a dimensionless constant that correlates to the strength of the material. Materials can also be surface (case) hardened and then the bulk material will be soft and the surface will be hard, this is typical for items like gears and cams that have rolling wear but are not very heavily stressed to require bulk hardness. Most steel that is hardened is first machined to size and then hardened. If more accuracy is required, they are machined to just over net size, hardened and then ground to the final size as the heat treatment can change the size and shape a little as stresses are released. Some examples: Very hard steel (e.g. a higher quality knife blade): HRC 55–66 Axes, chisels, etc.: HRC 40–45 4140 Cr Mb Steel HRC 28 - 36 , bulk hardened to HRC 54, Nitride case hardened to HRC 60 P20 tool steel can be bulk hardened to over HRC 55 and then tempered down from HRC 51 to 28
- Q: How are steel coils protected against fire and heat?
- To ensure the safety of steel coils, various methods are used to protect them from fire and heat. One effective way is by applying a fire-resistant coating, which acts as a barrier between the steel surface and the heat source. This coating prevents direct contact and reduces the chances of ignition or damage. Aside from coatings, steel coils can also be stored in fire-resistant warehouses or storage facilities. These structures are built with fire-resistant materials like concrete or steel and equipped with fire suppression systems such as sprinklers or fire extinguishers. These measures help contain and suppress any potential fire, effectively limiting its spread and safeguarding the steel coils. Furthermore, facilities that handle steel coils often implement fire safety protocols and procedures. These may include regular fire drills, training programs for employees on fire prevention and response, and the installation of fire safety equipment like fire alarms and fire hoses. These measures ensure that any fire incidents can be quickly detected and addressed, minimizing the risk to the steel coils. Overall, protecting steel coils against fire and heat involves a combination of fire-resistant coatings, proper storage in fire-resistant structures, and the implementation of fire safety protocols. These measures work together to mitigate the risk of fire and heat-related damage, ensuring the integrity and safety of the steel coils.
- Q: What are the different thickness tolerances for steel coils?
- The different thickness tolerances for steel coils can vary depending on the specific requirements and industry standards. However, some common thickness tolerances for steel coils include: - Standard Tolerance: This tolerance typically ranges from ±0.005 inches to ±0.010 inches, meaning that the actual thickness of the steel coil can deviate within this range from the specified thickness. - Tighter Tolerance: In some cases, stricter tolerances may be required, especially for critical applications or industries. Tighter tolerances can range from ±0.002 inches to ±0.005 inches, ensuring a more precise thickness control for the steel coils. - Custom Tolerance: Depending on the specific needs of a project or customer, custom thickness tolerances can be defined. These tolerances can be either looser or tighter than the standard or tighter tolerances, depending on the application and the desired level of precision. It is important to note that different industries and applications may have their own specific tolerance requirements. For instance, industries like automotive or aerospace may require tighter tolerances due to the critical nature of their applications, while other industries may accept looser tolerances. Additionally, the specific type of steel being used can also impact the acceptable thickness tolerances. Therefore, it is crucial to consult the relevant industry standards and specifications to determine the appropriate thickness tolerances for steel coils in a particular application.
