Hot and Cold rolled steel

Understand the main differences between hot and cold rolled steel Hot and cold rolled steel are fundamental materials in the metal processing and manufacturing industries. Choosing between them isn’t about which is better, but about selecting the right material for the specific job. Understanding their distinct properties, manufacturing processes, advantages, and limitations is crucial for designers, engineers, and purchasers. The Core Difference lies in when and how the steel is rolled to achieve its final specifications 1. Hot Rolled Steel (HR): Process: Steel is heated significantly above its recrystallization temperature (typically above 1700°F / 925°C) until it glows. It’s then passed through rollers at this high temperature. Result: Easier shaping, […]

188 1810 and 180 Stainless Steel differences advantages and disadvantages

Comparing 18/8 18/10 & 18/0 Stainless Steels

NEWS / wanzhigroup

When you buy stainless steel cutlery or pots in the supermarket, you may have seen three different steel labels: 18/8 18/10 & 18/0 stainless steel. It is normal that these numbers are difficult for ordinary people to distinguish the difference, so what makes one stainless steel different from another? Which stainless steel is the best to choose? To quickly understand the differences between the three grades, here is a summary of the chemical composition, advantages and disadvantages of each stainless steel grade. 18/8 18/10 & 18/0 Stainless Steels Comparison Type Composition Pros Cons 18/10 Stainless steel Chromium-18% Nickel-10% Strongest commonlyused grade of stainlesssteel Highly anti-corrosive Resistant to piting Vuinerable tosaltwater

Will stainless steel rust?

NEWS / wanzhigroup

Stainless steel is widely praised for its durability and reputation as “stainless”, but many people still wonder: will stainless steel rust? The answer is under certain conditions. While stainless steel is highly resistant to corrosion, it is not completely immune. Why is stainless steel (mostly) rust-resistant? Stainless steel contains at least 10.5% chromium, which reacts with oxygen to form a thin, invisible, passive layer of chromium oxide on its surface. This chromium oxide layer acts as a barrier, blocking moisture and oxygen from reaching the underlying steel. When the steel is scratched, this chromium oxide layer will usually repair itself in an oxygen-rich environment, keeping the metal protected.However, this passive

Is high carbon steel harder or softer

NEWS / wanzhigroup

Uncovering the relationship between carbon content and material properties In industrial manufacturing and material selection, the hardness of steel is a key indicator. Many buyers and consumers often ask: “Is high carbon steel harder or softer?” This article will comprehensively answer this question from the perspective of carbon content, steel properties to practical applications, and provide professional advice on purchase and use. How Carbon Content Affects Steel Hardness The hardness of steel is mainly determined by its carbon content. High carbon steel usually refers to alloys with a carbon content of more than 0.6%, between 0.6% and 1.5%. While low carbon steel has a carbon content of less than 0.3%,

304 vs 316 Stainless Steel: Comprehensive Comparison of Key Differences

304 vs 316 stainless steel Differences

NEWS / wanzhigroup

This article explores the key differences between 304 vs 316 stainless steel to help engineers, purchasers, and consumers make an informed choice. Stainless steel is a cornerstone material of modern manufacturing, with 304 and 316 stainless steel dominating industrial applications. While both are austenitic stainless steels with similar properties, their differences in chemical composition, performance, and cost make them suitable for different uses. 1、Chemical Composition Differences The main difference lies in their alloying elements: 304 stainless steel: Contains 18% chromium and 8% nickel (18/8 grade) and no molybdenum. This composition provides strong corrosion resistance in mild environments. 316 stainless steel: Adds 2-3% molybdenum to enhance resistance to chloride-induced corrosion (such

How to Remove Rust from Stainless Steel

NEWS / wanzhigroup

Remove rust has always been a topic that cannot be separated from steel products. As stainless steel is known for its rust-free properties, will it rust? Although stainless steel is known for its durability and smooth appearance, even this corrosion-resistant material will rust when it comes into contact with moisture, salt or pollutants. Fortunately, rust can be removed from the surface of stainless steel using some common items or special products. Below, we outline proven methods to restore your stainless steel surfaces and prevent future rusting. 1、Basic Cleaning and Gentle Remove Rust Methods Use gentle methods first to avoid damaging the protective chromium oxide layer on the stainless steel surface.

Carbon Steel and Stainless Steel

NEWS / wanzhigroup

Carbon steel and stainless steel each have their own strengths. Carbon steel, also known as carbon steel, typically has a carbon content range of 0.0218% to 2.11% (mass fraction). When the carbon content exceeds 2.11%, it is generally referred to as cast iron. Stainless steel belongs to alloy steel, and its core alloying element is chromium (Cr, usually ≥ 10.5%). The carbon content of stainless steel ranges from 0.03% to 0.15% (mass fraction), and some ultra-low carbon stainless steels (such as 304L and 316L) even have a carbon content of ≤ 0.03%. Stainless steel, also known as “inox steel” (French “inoxydab” means “non oxidizable”), truly lives up to its name
