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.

Generally, steel round bars have specified tolerances for diameter, straightness, and length. For diameter tolerance, it is usual to find tolerances ranging from +/- 0.001 inches to +/- 0.005 inches. This means that the actual diameter of the steel round bar can deviate within this range from the specified diameter. The size and grade of the bar determine the specific tolerance. Straightness tolerance refers to the permissible deviation in the straightness of the bar. Typically, it is specified as a maximum deviation per unit length, such as 0.125 inches per foot. This ensures that the bar remains straight and within acceptable limits when measured along its length. Length tolerance determines the allowable variation in the overall length of the round bar. It can range from +/- 0.125 inches to +/- 0.5 inches, depending on the size and grade of the bar. This ensures that the bar meets the required length specifications. It is important to note that these tolerances can vary based on industry standards, customer specifications, and the manufacturing method employed. Moreover, certain applications may have stricter tolerance requirements, particularly in industries like aerospace or automotive where precision is crucial. To summarize, the tolerances for steel round bars encompass diameter, straightness, and length. The specific tolerances depend on the size, grade, and application of the round bar, as well as any relevant industry standards or customer specifications.
- Q:What are the different types of steel round bar surface finishes used in the marine industry?
- In the marine industry, there are several different types of steel round bar surface finishes that are commonly used. These finishes serve various purposes and have specific characteristics that make them suitable for specific applications. Here are some of the most common types of steel round bar surface finishes used in the marine industry: 1. Polished Finish: A polished finish is achieved by grinding the surface of the steel round bar to a smooth and reflective surface. This finish is commonly used in applications where aesthetics are important, as it provides a visually appealing and shiny appearance. Polished finishes are often used for decorative purposes on boat fittings, handrails, and other exposed areas. 2. Mill Finish: Mill finish refers to the surface condition of steel round bars as they come from the mill without any additional treatment. This finish is characterized by a rough and dull appearance, as it is not meant to be visually appealing. Mill finishes are typically used when a smooth or polished surface is not necessary, such as in structural applications or where the material will be painted or coated. 3. Shot Blasted Finish: Shot blasting is a surface treatment process that involves propelling small steel shots at high velocity onto the surface of the round bar. This process removes any surface impurities, scales, or rust, resulting in a clean and slightly textured finish. Shot blasted finishes are commonly used in marine applications where improved adhesion of coatings or paint is required, as the textured surface provides a better bonding surface. 4. Hot Rolled Finish: Hot rolled finish is achieved by subjecting the steel round bar to high temperatures during the manufacturing process, followed by rapid cooling. This process results in a scaly surface with a rough texture. Hot rolled finishes are suitable for marine applications where corrosion resistance is not a primary concern and where the material will be further processed or coated. 5. Galvanized Finish: Galvanizing is a process of applying a protective zinc coating to the surface of the steel round bar. This finish provides excellent corrosion resistance, making it ideal for marine applications where the material will be exposed to saltwater or harsh environmental conditions. Galvanized finishes are commonly used for boat trailers, marine hardware, and other components that require enhanced protection against corrosion. These are just a few of the different types of steel round bar surface finishes used in the marine industry. Each finish has its own unique properties and advantages, allowing for a wide range of applications in the maritime sector. The choice of finish depends on factors such as aesthetics, corrosion resistance, coating compatibility, and the specific requirements of the marine application.
