 Maxwell Steel analyzes five key parameters: material type, thickness tolerance, surface treatment, dimensional matching, and mechanical properties. Mastering these points ensures you select high-quality steel and optimizes your purchasing decisions. When sourcing steel coils, choosing the right parameters is crucial. As a professional steel manufacturer, Maxwell Steel analyzes five key parameters to help you make informed decisions. Understanding these details will ensure you receive high-quality steel products that meet your project requirements. 1. Material type: The foundation for steel coil performance The material of a steel coil directly affects its mechanical properties, corrosion resistance, and applicable environment. Common materials are mainly divided into two categories: Carbon steel(coil) ：With a carbon content of 0.05%-2.1%, steel can be classified into low-carbon steel (C≤0.25%), medium-carbon steel (0.25%＜C≤0.6%), and high-carbon steel (C＞0.6%). Low-carbon steel ...

  In steel procurement decisions, the cost difference between alloy steel plates and ordinary steel plates often causes hesitation among buyers. As a professional steel manufacturer, Maxwell Steel will analyze the performance-to-price ratio of both materials to help you choose the most economical solution based on your project budget. I. Definition and Core Differences Alloy steel plate is a special type of steel made by adding elements such as chromium, nickel, and molybdenum to carbon steel.  Its mechanical properties, corrosion resistance, and high-temperature stability are significantly superior to those of ordinary steel plates. According to the ASTM A387 standard, alloy steel plates can be divided into low-alloy steel (total alloy element content <5%) and high-alloy steel (total alloy element content >5%). Ordinary steel plates mainly refer to carbon structural steels such as Q235 and SS400, which have lower production costs but limited overall performance. II. Cos...

  In industrial applications, the selection of stainless steel pipes directly impacts engineering safety and service life. This article provides an in-depth analysis of the differences in corrosion resistance and pressure rating standards between 304 and 316 stainless steel pipes, helping procurement personnel choose the optimal solution based on media characteristics and operating conditions. As a professional steel supplier, we offer specific selection recommendations for common corrosion problems in the chemical and energy industries. I. Core Performance Indicators of Industrial-Grade Stainless Steel Pipes When selecting industrial-grade stainless steel pipes, corrosion resistance and pressure rating are two key indicators. 304 stainless steel pipes contain 18% chromium and 8% nickel, making them suitable for general corrosive environments; while 316 stainless steel pipes have an additional 2% molybdenum, performing better in chloride environments. According to the ASTM A312 sta...

  In industrial piping system design, flange selection directly impacts project safety and cost-effectiveness. As a core component of pipe connections, the material, pressure rating, and sealing performance of a flange are the three key factors in its selection. This article will provide an in-depth analysis of how to choose the most suitable flange solution based on operational requirements, helping engineers avoid common selection pitfalls. I. Material Selection: The Core Factor Determining Flange's Corrosion Resistance and Service Life The material for industrial-grade flanges needs to be comprehensively evaluated based on the characteristics of the medium, temperature, and environment. Carbon steel flanges (such as ASTM A105) are suitable for conventional water, oil, and steam systems, offering excellent cost-effectiveness; while 304/316 stainless steel flanges are designed for acidic, alkaline, or high-salinity media, as their chromium-nickel content forms a passivation film ...

Technical Comparison of Steel Weight Calculation Methods In steel trading and engineering applications, the accuracy of weight calculation directly impacts material procurement budgets, logistics cost accounting, and structural safety assessments. The competition between traditional manual calculations and digital tools (steel weight calculators) is essentially a microcosm of an industry efficiency revolution. This article will provide an in-depth analysis from three dimensions: calculation principles, error control, and scenario applicability, to help purchasing managers, structural engineers, and other professionals make informed technology selection decisions.     The Underlying Logic Differences in Calculation Principles Manual calculations rely on the classic physical formula: Weight = Volume × Density. For standard profiles such as H-beams and angle steel, the cross-sectional area must first be calculated using the cross-sectional dimensions, and then multiplied by the l...

Q235B is a carbon structural steel, conforming to standards GB/T 700-2006 and GB/T 3274-2017, formerly designated C3. In its designation, "Q" represents the yield strength, "235" indicates a lower limit of 235 MPa, and "B" signifies a grade B killed steel. Its chemical composition includes elements such as C≤0.20%, Mn≤1.4%, Si≤0.35%, P≤0.045%, and S≤0.045%, exhibiting good plasticity, toughness, and weldability.
