FAQ:
Q1: What makes stainless steel stainless?
A1: 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.
Q2: Can stainless steel rust?
A2: 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.
- Q: Can a steel square be used for checking the plumbness of a column?
- No, a steel square cannot be used for checking the plumbness of a column. A steel square, also known as a framing square or carpenter's square, is primarily used for measuring and marking right angles in carpentry and construction work. It consists of a long, straight edge with a perpendicular arm, forming an L-shape. While it can be useful for tasks such as checking angles or laying out cuts, it does not have the necessary features or accuracy to determine the plumbness of a column. To check the plumbness of a column, a plumb bob or a level would be more appropriate tools. A plumb bob is a weighted object attached to a string, which when suspended, aligns itself vertically due to gravity. By holding the plumb bob against the column, one can determine if it is perfectly vertical or not. On the other hand, a level has a bubble that moves within a vial, indicating whether a surface is level or plumb. By placing the level against the column, one can easily check if it is perfectly plumb or if it requires adjustment. In summary, while a steel square is a versatile tool in construction, it is not suitable for checking the plumbness of a column. A plumb bob or level should be used for this specific task to ensure accurate results.
- Q: How do you use a steel square to mark out parallel lines?
- To use a steel square to mark out parallel lines, you will need a few basic tools such as a pencil, a steel square, and a straight edge. First, place the steel square on the surface or material that you want to mark the parallel lines on. Ensure that one edge of the square is aligned with the starting point of your desired line. Next, hold the square firmly in place with one hand, making sure it doesn't shift during the marking process. With your other hand, take the pencil and place it against the edge of the square, ensuring that it is in contact with both the edge of the square and the surface of the material. Now, while keeping the pencil in contact with the edge of the square, slide it along the length of the square, allowing the edge of the square to guide the pencil and create a straight line. Continue this process until you have marked out the desired length of the parallel line. Repeat the above steps for each parallel line you want to mark out, making sure to align the steel square with the starting point of each line. It is important to note that the accuracy of your parallel lines depends on how well you align the steel square and maintain contact between the pencil and the edge of the square throughout the marking process. Additionally, using a straight edge in conjunction with the square can help ensure your lines are perfectly straight and parallel.
- Q: How do you use a steel square to measure board thicknesses?
- To measure board thicknesses using a steel square, follow these steps: 1. Choose a steel square with an appropriate length tongue and blade. The tongue is the shorter side, and the blade is the longer side. 2. Place the steel square on a flat surface, ensuring that both the tongue and blade are in contact with the surface. 3. Position the board you wish to measure against the tongue of the steel square, making sure it is perpendicular to the square. 4. Slide the board along the square until its opposite edge touches the blade. Maintain the board's flatness against the surface. 5. Take note of the measurement where the board's edge intersects with the blade of the steel square. This measurement indicates the board's thickness. 6. To ensure accurate results, repeat the process at various points along the length of the board. If there are any variations, calculate the average measurement for precision. Utilizing a steel square for measuring board thicknesses is a straightforward and reliable technique that yields precise outcomes.

- Q: How is a steel square different from a combination square?
- A steel square and a combination square are both measuring tools used in carpentry and metalworking, but they have different features and purposes. A steel square, also known as a framing square or carpenter's square, is a large, L-shaped tool typically made of steel or aluminum. It has two arms, one longer than the other, and is primarily used for measuring and marking right angles. The longer arm, known as the blade, is usually 24 inches long, while the shorter arm, called the tongue, is typically around 16 inches. Steel squares are commonly used in construction for tasks like framing, laying out stairs, and checking for squareness. On the other hand, a combination square is a versatile measuring tool that consists of a ruler or blade with an adjustable head that can be locked at different angles. The head of a combination square has a level bubble, a protractor scale, and a scribe or marking point. Unlike a steel square, a combination square allows for precise measurements, including both angles and lengths. It is commonly used in woodworking, metalworking, and other trades where accuracy and versatility are important. Combination squares are useful for tasks such as measuring and marking 45-degree and 90-degree angles, setting up miter cuts, and transferring measurements. In summary, the main difference between a steel square and a combination square lies in their design and functionality. A steel square is a simple L-shaped tool primarily used for measuring right angles, while a combination square is a more sophisticated measuring tool that can measure angles and lengths with greater precision and versatility.
- Q: How do you use a steel square for determining the center of a circle?
- To use a steel square for determining the center of a circle, you can follow these steps: 1. Begin by drawing a straight line across the circle's diameter using the steel square. Place the square on the circle's edge, ensuring that it intersects the center of the circle. 2. Make a mark where the straight line intersects the circle on both sides. These marks will serve as reference points. 3. Rotate the steel square and place it on the circle's edge again, aligning one of the square's edges with one of the reference points you just marked. 4. Draw a second straight line across the diameter of the circle, intersecting the center and the other reference point. 5. The point where the two lines intersect is the center of the circle. You can mark this point or use it as a reference for further measurements or constructions. Using a steel square for determining the center of a circle provides a precise and accurate method, ensuring that your measurements are consistent and reliable.
