Timeline graphic of eight TFS purchase orders placed by the Bolivian distributor

How a Bolivia Buyer Went From a $53 Sample to an 8th TFS Order

On October 20, 2026, we shipped 120 tons of tin free steel (TFS) to a distributor in Bolivia. It does not sound unusual until you learn it was their eighth order with us since April 2025, and that the relationship began with a sample worth just $53. This post walks through that growth, the product that holds it together, and why repeat orders like this matter more than any single shipment. 1. The Shipment That Closed Out Order Eight On October 20 we loaded 120 tons of TFS and sent it toward Bolivia. For most suppliers that is a routine booking. For us it closed the customer’s eighth purchase order

Marine grade stainless steel sheet with brushed surface treatment

Marine grade stainless steel sheet

Marine grade stainless steel sheet Width: 600-1250mm or customizable Thickness:  0.13-6.0mm Design Style:  Customizable This page covers what makes 316 the marine grade, what chemistry and strength to expect, what sizes sheet comes in, and how to order it. The numbers come straight from our stock list, so you can turn them into an RFQ as you read. What is a marine grade stainless steel sheet? “Marine grade” is a trade nickname, not a standard name. When buyers use it, they mean 316 stainless steel in sheet form: cold-rolled flat product, 3 mm thick or under, with a surface ready for cladding, fabrication or further polishing.

Microstructure diagram of austenitic 304 next to ferritic 430 stainless steel

304 vs 430 stainless steel: magnetic, cost and welding compared

When buyers line up 304 vs 430 stainless steel, the first surprise is the magnet. Hold one to 430 and it sticks hard. Hold it to 304 and it barely reacts. That single test points to a deeper split: 304 is an austenitic, nickel bearing grade built for food, weather and welding, while 430 is a ferritic, almost nickel free grade built for indoor trim and low cost. Both resist rust in ordinary air, but they part ways on magnetism, price and how they behave under a welding torch. This guide puts them side by side on chemistry, corrosion, cost, weldability and use, so you can pick the right one

Stainless steel price guide 2026

If you are budgeting a job in 2026, the first number you need is the stainless steel price per kg, and the second is the direction it is moving. This guide puts both on the table. In 2026, 304 base product runs about 2.90 to 3.80 USD per kg and 316L runs about 4.00 to 5.00 USD per kg before finish, freight and alloy surcharge. The ss price trend this year has been a slow climb: 304 opened near 2,800 USD per ton and held a 2,800 to 3,200 USD band through the second half, up about 8 percent year over year, while 316 drifted higher on molybdenum cost.

316 vs 304 stainless steel complete comparison

316 vs 304 stainless steel: complete comparison guide

When buyers line up 316 vs 304 stainless steel, the question is almost always the same: do I really need the pricier 316, or will 304 do the job for less? Both are austenitic 18/8 grades, both look alike on the rack, and both weld and polish well. The one element that separates them is molybdenum. 316 carries 2 to 3 percent of it, 304 does not. That single addition is what lets 316 shrug off chloride and salt while 304 pits and rusts in the same spot. This guide puts the two grades side by side on chemistry, corrosion, cost, weldability and use, so you can specify the right

316L and 316 stainless steel plate composition

316 stainless steel plate

316 stainless steel plate Width: 600-1500mm or customizable Length: 1-12 m Thickness:  3-120 mm The 316 stainless steel plate is a flat-rolled strip of austenitic stainless that carries 2 to 3 percent molybdenum, which is what sets it apart from 304. That molybdenum gives 316 its resistance to chloride pitting and crevice corrosion, so it is the grade buyers choose for marine, coastal, chemical and food work that sees salt or acid. We stock 316 plate in 3 to 120 mm and widths up to 2000 mm, and we cut it to size before it leaves the mill. This page covers what 316 plate is made of, how it performs,

304 stainless steel plate

304 stainless steel plate Width: 600-1500mm or customizable Length: 1-12 m Thickness:  3-120 mm Design Style:  Customizable 304 stainless steel plate is a flat-rolled strip of 18/8 austenitic stainless that is thicker than 3 mm and sold as plate rather than sheet. It is the grade most buyers reach for when they need corrosion resistance without paying for molybdenum, and it welds, cuts and forms well enough to suit tanks, cladding, frames and food equipment. We product 304 plate in thicknesses from 3 mm to 120 mm and widths up to 2000 mm, and we cut it to size before it leaves the mill. This page covers what 304 plate

PPGI coil Kenya RAL 7021 PPGI coil color swatches

PPGI Coil Kenya: 452T in Two Orders, PVOC/COC Cleared

A Kenyan distributor opened an inquiry with us on July 12, 2026. Five weeks later they had placed two separate purchase orders for color coated steel coil (PPGI), 226 tons each, and the second payment just 15 days after the first payment. The trigger for that second order was simple: the first batch came off the line, the customer’s appointed third-party agency ran the mandatory PVOC/COC inspection, and it passed. This post walks through the full specification, the RAL color mix, why the gauges are thin, what Kenya’s PVOC/COC actually checks, and why a clean inspection result turns into a repeat order faster than any sales pitch.

Two stainless steel pipe and tube samples, one marked A312 and one marked A269, lying side by side on a bench

ASTM A312 vs ASTM A269 stainless steel pipe: which one to choose

When buyers compare ASTM A312 vs ASTM A269 stainless steel pipe, the first question is usually which one the job actually needs. The short answer: A312 covers stainless steel pipe for higher pressure and temperature service, while A269 covers stainless steel tubing for general service where tight tolerances and a clean surface matter more than rated pressure. Both specs describe austenitic stainless in grades like 304 and 316L, so the material looks the same on the rack. The difference is in how the product is sized, tested, and what it is built to survive. This guide walks through the two standards line by line so you can specify the right
